TV broadcast bodywork design requirementsIntroduce bodywork designInstall broadcast is a comprehensive system engineering, the body is the complex system is an important part of. In the broadcast, the body part in carrying out all broadcast video recording needed, audio and peripheral equipment, provide an outside the workplace. Not only such, still must ensure the safety equipmentoperation and smooth transhipment, The design quality, not only directly affect the task of broadcast programs, but also to the whole system of safe transport equipment.Bodywork design, is the first consideration in the broadcast of the design, the first thing to do, It will have a direct relationship to other system design.Bodywork designing technical requirements for design, should according to the hull of broadcast equipment size and purpose to choose, The general is installed cameras number, the risk is bigger also. According to the former chapter 8, use the broadcast cameras, can consider to choose medium broadcast. In television broadcast often faced severe external environment, and considering carrying equipment and broadcast task too many factors such as particularity, broadcast in the modification of car when the car to the body, structure and so on a series of chassis project careful overall consideration, through special design and processing, can meet the basic requirements of television. The following are the technical requirements for design body.The safety performance of the broadcast must conform to the state auto industry standards, car body processing and chassis USES the overseas broadcast depot exterior processing technology, size and payload must conform to the state department of traffic regulations. Car chassis and selection: international famous brand high-end products, the truck chassis on all equipment shall be loaded under the condition of the truck with 20% less than 200 surplus, engine, air suspension design, power electronic speed, hydraulic control 85KM/h, air conditioning system design, driving with anti-lock brakes (ABS) emission standards, with European standards, 111 2.5 meters wide.Car body requirements: TiZong compartments 10-11 meters long, no more than is 3.8 meters high and wide 2.5 meters, the right side is four meters long pull box. Box body use fixed number of year more than 15 years, the car body structure of aluminum alloy frame, with high strength and insulation, Material requirement is accord with international standard of environmental protection, flame retardant materials. Vehicle requirements, dustproof, waterproof and sealed anti-rust, anticorrosion, preventing electromagnetic interference, antistatic, After the integration of box body must be rain experiment (including the side after pulling open box, when jose) experiments, the static pressure side tilt impact experiment. The surface with high strength and durable products in the process of paint, paint baking room. Body after processing, vehicle has left from the Angle, finally, from the smallest drive vehicle spacing, minimum turning radius basic technical parameters.Body: the space layout design requirements, and fully consider the reasonable layout of the camera, lens, earphone, tripod, cable, microphone, tools and equipment accessories storage space. For the car fixed equipment should consider appropriate carry scheme.In the national standard of vehicles, within the scope of the space as far as possible, spacious internal headroom maximization, the lateral pull section 2.2 meters, internal clear part and internal headroom wife 2.0 cars, cars GaoCheng 4 meters in vitro.According to the different type of programme production division, scientific and reasonable utilization of working space. The workspace shouldHave partition, and pass the adornment with door, audio broadcasting acoustic requirements.Car chassis and selectionGenerally speaking, the car chassis and is generally together of choose and buy, the first to calculate the weight, then the broadcast and calculate the maximum weight, total quality, Choose total capacity calculation model is bigger than that.This design calculation, for example (hereinafter data for each half xiang estimated) :The total weight of two car electronic equipment nominal total weight (1 ton) + internal cables and connectors total weight (0.3 tons) ten outsideCable and cable reels total weight (0.5 tons of air-conditioning equipment and power) and total weight (l) + containing side and tons of heavy trunk TiZong compartments (5 tons) + car chassis total weight (5.5 tons) = 13.8 tons. Maximum loading 17.25 tons.Additionally, want to consider the traffic situation and task destination of local geography environment, For been poor road conditions or the environment, should choose the output power of the engine and have left corner to corner and Outlines the chassis (in after modification, this part of the parameters change), In order to protect the precision bearing, should choose the equipment with air suspension design of air suspension system (increase chassis, can effectively increase the stability and the operation is necessary in the smallest increase car from the ground clearance and increase the car go right Angle of comparison, through calculation. Head and chassis selection for: Germany, MANLE18.280 car chassis and 18 tons, the highest quality of loading, electronic power output of 280 horsepower maximum speed did 85k: / h, exhaust emission standard requirements, chassis for double-axis braking, rear suspension system (air adjusting range to 14Omm - 80mm), to 18.5 Angle (left), (6.5 Angle, hydraulic steering system, ABS system.Bodywork design types and carsBody type selection, according to the technical requirements for broadcast medium body choice to build. At present, we have the choice of two types: the body dragged hang cabinet type body and direct box type bodywork. Straight hang cabinet is cabinet of body directly placed in vehicle chassis. Drag hanging box type body is only a few on-axis (l), or on the trailer to move. Now broadcast and dimensions of the body, but are strict standard practice. Straight hang cabinet body type hanging box type than drag of small size, because the body size by means of transport together for this decision, countries have limited body length. Generally speaking, it adopts the body from 8 to 10 metres, car - 10-12 meters to. Drag hang cabinet type body USES is 13.6 meters standards body length, but due to the design needs may be more or less. For example, do the length of 18 meters above the hull. Considering the high road, there is through the general standard limits, cannot exceed 4 meters high, usually for 3.7-390 meters, width is 2.5 meters. Because of this part of the city and the surrounding roads are narrow, many sites around the gate, and narrow space, low broadcast to think of site near the area is restricted, models. Additionally, the demand is moderate, considering the number of these factors, so the choice of pull with lateral direct box type car. Hang cabinet type body straight by lateral pull cars, can expand workspace technology area, reduce the length of the body and the height, make whole have shorter turning radius, and good road through sex, increase flexibility of moving body. Drag hanging bodywork, high center of gravity, stability, not only in the city driving speed is slow, even in the highway is compared with straight, and drag hang trailer for highway and car case typed driver requirement is high. However, until the body hangs box type, the car chassis and broadcast is permanently connected compartment, Because of the reliability of the car and car box part is the reliability of the chassis, therefore the reliability of the system reliability of normal operation. However, in the car with tow lock, in case.Car body designThe whole system design is compartments of the follow-up work, it relates to broadcast other system design. In the initial stage of design, construction, as a first consideration should choose the material, then compartments of air conditioning, consider bodywork layout and installation requirements of technical equipment, etc； put At the same time, the design details must be considered the perfect follow-up function. The car body from design to completion, need at least 4 to 5 months. Various processes are certain order, therefore, in the design of the system should have planning and management. Car layout. The car compartment, broadcast early material body USES a lot of hardwood as their framework with the period, the most commercial body design, In the 1960s began to aluminum frame, aluminum envelope special design direction. 4 when turning radius: automotive steering wheel steering, car outside the center, under support vehicles, track circle radius. Steering wheel turned to limit position for minimum radius of turn ramming turn radius of glory. Now, a better and more stable fiber materials of aluminium surface (aluminum) chromate salt a sandwich board structure of interlining, Therefore, most use these new materials and structure to build the whole body, the conventional materials is added as internal store content ark, entrances, and other auxiliary area.Through the comparison, FRP (GRP6 or FRP6) or aluminium surface material qualitative sheet intercalation sandwiches are high, with design, long service life, magnetic, insulation, sound insulation, etc.Sandwich board, according to the different surface material, is divided into: steel surface materials and aluminum/GRP surface materials. When the materials of large area, steel surface material can produce vertical crease, and aluminum/GRP surface materials (not crease) consecutive. In addition, the surface of aluminum excellent in reason, including anodized, apparent into processing, coating and electroplating, therefore, to broadcast, choose aluminium surface or surface suitable materials.For frame materials (stainless steel and aluminium), we fully consider the various factors. Stainless steel welding joint with high mechanical strength, rigidity and fatigue resistance, can satisfy the demand for hull integrity structure. Among the austenitic stainless steel, with excellent energy absorption ability, considering safety construction, it is elected. In the vehicle weight after comparison, choose steel material than aluminum material slightly heavier 10%. Through comparing, aluminum plate type: the surface of metal sheet intercalation sandwiches and mixed structure of the body. This bodywork austenitic stainless steel body frame structure (profiles do using stainless steel welding aluminum easier than because of stainless steel, aluminum) sandwiches sandwich plate surface of car do. For Windows and doors, choose body surface sandwich sandwich plate GRP. Box body side sandwich sandwich plate thickness 50 cars, total body top sheet intercalation 55mm thick sandwiches, the total volume of reinforcement and the cabins lockers by certain thickness of stainless steel. This new design of body structure, give full play to the advantages of two kinds of materials, and make a new body than the current domestic other body, has more advantages than traditional vehicle weight of car-body reduce 40%, Aluminum/GRP materials sandwich insulation sandwich board, make car is very quiet, Body structure is due to decorate, Car body USES sandwich plate containing special since maintain sandwich super structure, high strength, good resistance to impact and the support ability, to ensure the long-term stability of the hull structure, can reduce maintenance costs. In addition, sophisticatedelectronics wooden store content ark, the table at the edge of the wooden edge material selection, was processed by the hardwood, insect and moistureproof, Rappel/abseil stations should be at the man-made fabrics such as screen window instead of natural.The design and processing of carriageWhen a detailed schedule chart, after the completion of the body frame can from inside to outside began to build. From the bodywork design to completion probably need 4-5 months, then consider all equipment purchase, If the plan is completed in body, thoughtful, you can install equipment. At the beginning of the process, frame first is fixed on the car chassis rack. For special car body, chassis rack and body between the special elastic adhesive filling, can guarantee the bodywork multiple components in their long remain relatively fixed position, extended body life. When the body, the engineer will cabins sandwich plate design requirements by large Windows, doors and maintenance (etc), calculated platform, dig, then without fixed whole car chassis. For different area, we adopt profiles between sheet buckles after heightenning strength the special adhesive elastic method, minimum connection screw fastening and reduce the use of welding, hardware are stainless steel. In addition, in need of welding, choose good welding materials electroplating. On roof and floor, also used similar plank and processing method, But in these areas under the floor and big flower board inside, must design the air conditioning intake on spear strike price, exhaust pipe and cable etc. Air inlet 11 feet by ten working area through porous ceiling is completed, therefore essential in insulation layer under the appropriate design of pipe, In the porous metal plate, aluminum materials, and should choose the eye. The air filter condensation prevention. In order to avoid air turbulence generated in pipe noise, the design of many such pipe, the number of air conditioning, these specifications depending on pipes adopts non-toxic ammoniac Yun foam body. For simplified equipment maintenance, design the level off and maintenance. After repair, below half open platform made floor, ceiling upper, which makes it very convenient maintenance maintenance personnel. Maintain doors equipped with gas leading hoop, can easily open doors: all of the mouth, and the dust, shimei, and under the unified set with a key can open all the lock of the door. On both sides of the car body skirt locker, design for the camera lens, the tripod, backup, cable, tools and equipment store empty, They are designed to key can open mode. Because the body with cars, so in design and installation of the bottom side pull the two squares retractable cable protection pipe, through the cable from here to the body of internal also should be carefully considered. Within the sound broadcast require special environment, and therefore must choose sound-absorbing materials of wall and ceiling, we choose is porous sound-absorbing board (belong to impedance compound aluminum mufflers), internal filling composite sound-absorbing material. Car floor selects anti-static floor, easy cleaning. In the equipment design, the frame and the console keep back the gap in 50, This is after wiring brought convenient, also increased the equipment of cabinet, in order to control temperature air circulation. For the broadcast from appearance, can choose their own cars in the standard color swatches, so the color to the international standard RAL9010 color car choose pure white (to go out at the camera calibration quick white balance). After the integration, car body 10.06 presidents, total height 3.75 m, width 2.5 m, right side, 4m bandwidth, can pull lm. The manufacturer to rain experiment box body (including the lateral spread), full pull box when inclined to static experiment, high impact experiment, Meet the design requirements. When our car modified in the rear car modification, rear skirt do for design of dress, car tilting such modified normal operation technical parameters for the final horn, left: from high 437mm, driving the minimum distance from the ground. Minimum turning radius, the vehicle 9.65 m.Bodywork layout designThe number of hull layout including partition door, the work area, etc. According to the practice of the body, broadcastIs divided into three separate areas: director area, centralization, audio area. With the setting TV production, more standardized, scientific and set each region also distribution and the corresponding locations.電視轉(zhuǎn)播車車體的設(shè)計(jì)要求車體設(shè)計(jì)介紹安裝轉(zhuǎn)播車是一項(xiàng)綜合性的系統(tǒng)工程，車體是這個復(fù)雜系統(tǒng)的重要組成部分。在整個轉(zhuǎn)播車中，車體部分承載了所有轉(zhuǎn)播錄制所需要的視頻、音頻及周邊設(shè)備，提供了室外工作的場所。不僅如此，車體還必須保障設(shè)備的安全運(yùn)行和順利轉(zhuǎn)運(yùn)；其設(shè)計(jì)的好壞，不僅直接影響節(jié)目制播任務(wù)的完成，還關(guān)系到運(yùn)送整個系統(tǒng)設(shè)備的安全。車體設(shè)計(jì)，是在轉(zhuǎn)播車設(shè)計(jì)中最先考慮的，也是首先要做的；它的好壞直接關(guān)系到以后其他系統(tǒng)的設(shè)計(jì)。車體設(shè)計(jì)技術(shù)要求車體設(shè)計(jì)，應(yīng)該按照轉(zhuǎn)播車的設(shè)備規(guī)模和使用目的來選擇；一般是安裝攝像機(jī)的訊道數(shù)越多，車體也就越大。按照 所 ，使用 攝像機(jī)的轉(zhuǎn)播車， 以考慮選擇中 轉(zhuǎn)播車。電視轉(zhuǎn)播車 的 外部 ，以及考慮到承載設(shè)備的 性和轉(zhuǎn)播任務(wù)的 性 多，轉(zhuǎn)播車車體在 裝 必須 車的 、車體 一系 項(xiàng)目 行周的全 考慮， 設(shè)計(jì)和工，currency1“電視轉(zhuǎn)播的要求。fi fl 車體設(shè)計(jì)的技術(shù)要求。轉(zhuǎn)播車的安全性currency1必須合車行 的關(guān)，車體工及 ”用外轉(zhuǎn)播車工技術(shù)，外 及有 載必須合 部的關(guān)規(guī)。車和 選 要求 的 ， 的載重應(yīng)在裝載所有設(shè)備的fi有 以 的載重 ， 不 ，設(shè)計(jì)，電 ， 制系統(tǒng)， 設(shè)計(jì)， 備 車 ， 合，車 。車體要求體 1 -11 ，整車不超3 ， ，右部有4 的側(cè)拉箱。體使用年 十五年以 ，車體框架由鋁合金夾層 組成，有較的強(qiáng)度和絕緣性；所用材料要求是合的 保、阻燃材料。整車要求封， 塵、 水、 銹、 腐蝕， 電磁干擾、 靜電；集成后必須 體 行淋雨實(shí)驗(yàn)包括側(cè)拉箱展開后 ，“ 行靜態(tài)側(cè)傾斜實(shí)驗(yàn)， 沖擊實(shí)驗(yàn)。外表 ”用 保 強(qiáng)度耐用 油漆，整個噴漆程在烤漆房 行。車體工后，要求車輛有合適的離去角、最后離地、行中最 離地間距、整車最 轉(zhuǎn)彎半徑 技術(shù)參數(shù)。車體布局設(shè)計(jì)要求 間布局合理，并充分考慮攝像機(jī)、鏡、耳機(jī)、三腳架、備用線纜、話筒、工具設(shè)備器材及其附件的存 間。 非車內(nèi)固定設(shè)備應(yīng)當(dāng)考慮合適的攜帶方案。在車輛范圍內(nèi)， 間盡 currency1的敞，車體內(nèi)部凈最大化，非側(cè)拉部分內(nèi)部凈 ，側(cè)拉部分內(nèi)部凈妻 ，車體外成4 。按照節(jié)目制作的不同工種劃分工作區(qū)，科學(xué)合理的利用 間。各工作區(qū)之間應(yīng)當(dāng)有隔斷，并有行，音頻區(qū)的裝飾合廣播聲學(xué)要求。車和 選 一般來說，車和 一般是連在一起選購的，首先要計(jì)算整個轉(zhuǎn)播車的載重 ，然后 自重，計(jì)算 其最大 質(zhì) ；選擇 承重略大 計(jì)算 的 。以此設(shè)計(jì)計(jì)算 以fi數(shù) 半 各 算 車 重 電 設(shè)備 重1 內(nèi)部電纜和連接 重 3 十外部電纜及電纜 重 設(shè)備和電 重 側(cè)拉后車體 重 車 重 13 ；最大裝載質(zhì) 1 。外，要考慮任務(wù)目的地道 行 和當(dāng)?shù)氐牡乩?； 多 地 道 件較 的 ，應(yīng)選擇 較大的 和 有較大接 角和離去角 的 在車體 裝后，這部分參數(shù) 化 ； 了保承載的設(shè)備，應(yīng)選擇帶有 設(shè)計(jì)的 系統(tǒng)，currency1有 地車行運(yùn)中的定性和在必要 車的最 離地間右、大車的離去角。計(jì)算較， 車和的選 currency11 車和 ，最大裝載質(zhì) 1 ，最 ，電 行最車 “ ， 到要求， 制fi，后fl有 系統(tǒng) 整范圍到-14 ，接 角1 ，離去角 ，有 轉(zhuǎn) 系統(tǒng)，有 系統(tǒng)。車體 及體設(shè)計(jì)車體 選擇 技術(shù)要求，此轉(zhuǎn)播車按照中 車體選擇。目 ，供”選擇的車體有種 箱體 車體和直 箱體 車體。直 箱體 車體是箱體直接安 在車輛 。 箱體車體是僅有后 個 個 的，車來fi。在轉(zhuǎn)播車車體并有的，有。直 箱體 車體要 箱體 車體的 ，這是 車體由連在一起的運(yùn) 工具定， 這的車體 度有一定的 定。一般來說，它”用的車體 到1 之間，車 到1 - 1 。 箱體 車體”用的是13 的車體， 度由 設(shè)計(jì)的需求 currency1 多 。 如，有做到 度到1 以 的車體?？紤]到道 性，度是有 制的，一般不currency1超4 ， 的度 3 - 3 ，度 是 。由 和周邊的部分道 較 ， 多場地周圍 間 ，并 大較 ，轉(zhuǎn)播車要 到場較 的地區(qū)工作，車 到了 制。 外，設(shè)需求的訊道數(shù)適中，考慮到這 ， 此選擇了帶側(cè)拉的直 箱體 車體。直 箱體 車體”用側(cè)拉技術(shù)， 以 大工作 間 ， 車體的 度和度，使整車有較 的轉(zhuǎn)彎半徑，和較好的道 性，車體fi的 性。 車體 大、重較， 定度較 ，不僅在內(nèi)行車度 ，使在 也 直 車，還有 箱體 車體 和 的要求也 。是，直箱體 車體的轉(zhuǎn)播車，其車 和車體是 連接的；由 車箱體部分的 性 車 的 性是整個系統(tǒng)的 性， 此其 行的 性 了。不， 以在車內(nèi) 備，以備 一。車體設(shè)計(jì)體設(shè)計(jì)是整個系統(tǒng)后 工作的 ，它關(guān)系到轉(zhuǎn)播車其它系統(tǒng)的設(shè)計(jì)。在體設(shè)計(jì)的最 ，要首先考慮選擇 體的材料，然后考慮車體布局、 的需求和安裝、技術(shù)設(shè)備的 ；同 在設(shè)計(jì)的 節(jié) ，必須考慮后 currency1的完 。整個車體 設(shè)計(jì)到完工，需要4到 個 。各種工是有一定的順 ， 此，在設(shè)計(jì) 要有系統(tǒng)的規(guī)劃和理。車布局。車體的選材 ，轉(zhuǎn)播車車體使用了大 的 作 它的框架，這 那個 多數(shù)商
