6、 automobile industry has reached more than 1 million per year. This is only the demand for small bridge cars, with a total vehicle production of more than 1.5 million vehicles. At present, the market is dominated by cars. At present, all automotive companies produce heavy, medium and light models, i

7、ncluding cars, trucks and SUVs as the leading industry. Of course, most of the cars are already the mainstreanrnow. Cars need a very high technological level for their own manufacture, and the demand is also very large. Precisely because of the huge demand, So what he represents is the overall level

8、 of industrial development in a country; as a personal step. Tools, the future market of the automobile industry is also quite huge. With the improvement of the daily average level of people, the automobile market is developing in an irresistible way, compared with those in the mature period of the

9、international automobile industry. Car as the mainstream has become an inevitable choices, ide as an important part of the external decoration, integrated the car door frame and other important accessories. It has great significance in research. According to the structural characteristics of side gi

10、rth, combined with ergonomics and collision safety, the design and modeling of vehicle side girth are emphasized.The body of the body is mostly side wall. The side enclosure is the base of the side. The side plate is in the decisive role in the whole body development process, limiting and affecting

11、the welding sequence and welding connection in the body manufacturing process. The design time is more than half of the whole body design process, in the process of designing the product and manufacturing process of the mould. It also occupies a large proportion. The development of the whole body de

12、sign will be affected by the development process of the side and external parts. This requires that we carefully consider and study the layout of the side plates and the layout of the components that match the side pa nels at the beginning of the design and development. Do not change the side circum

13、ference of the component design. According to the A aspect of the vehicle, consider the requirements of the process and demonstrate the productionof the model. Side panels are designed on the basis of side panels andypical profile lines. And the welding relationship of the whole body should be consi

14、dered and the welding sequence should be set to ensure the overallstrength of the side girth. If the larger surface is modified, the layout of the device in the design room wil l need to be redesigned. After all, car side design is an important component of body design.The role of the body side circ

15、umference assembly is: A. Commuters and drivers are able to enter and leave the cab normally. Sealing, waterproof, dustproof, sound insulation, etc. Connect the floor, front, top, and back girth to form an inner and outer body. Install and bear forces from various functions and ornaments (such as se

16、atbelt pull, door handle pull, etc.). Bear all kinds of torsion from thewhole vehicle and the collision force to protect the safety of passengers.The side girth assembly is usually welded by the side outer plate, the side ring inner plate, the side girth strengthening plate and so on, thus the const

17、ruction becomes a whole, which impel the body to form a closed structure and improve theoveral strengthof the body. In order to effectively protect the safety of passengers and drivers.Ergoomics is a very important problem in the process of bod y design. This requires that we must have a certain und

18、erstanding of the side circumference. If divided from the functional aspect, the side-by-side system can be divided into three categories: basic body, functional parts , decorative parts. For the design of the side-girth system, its base piece is the side-girth. However, the basic side of the functi

19、on is the following two: support protection and is installed.The side plate is often regarded as the skeleton of the car and the vibration and load between other parts of the body. In addition, it is also an indispensable part of other body components connected.From the point of view of protecting p

20、assengers, I think the traditional side walk can be considered as a three-dimensional topology. It should be able to use the deformation of its own materials in a series of traffic accidents, such as vehicle collisions, overturning or other equipment, to reduce impact and reduce energy transmission.

21、 In the frontal collision of vehicles, the cockpit can absorb the impact through the deformation of the side wall in the collision accident, reduce the degree of deformation of the cockpit, and ensure the survival space of the passengers. In side impact and rollover accidents, the side plate needs t

22、o provide a very small volume of deformation to reduce the impact energy and facilitate the flight of the crew.Through the research and development of the body side body system, the design method of the body side circumference is understood step by step. By optimizing the body design and studying th

23、e development of portable body, this paper provides a reference for the development of environmental protection and energy saving vehicles in the future. This paper tries to catch up with the design ideas andmethods of the traditional automobile giant countries, accumulate the experience of the futu

24、re development of the automobile body in China, and produce high performance vehicles suitable for all the people through the combination of ergonomics.2. The content and implementation method of the thesisThe essence of the rapid development and modification of the side girth is to automatically up

25、date the side-by-side model according to the original default design standards and geometric constraints when the overall design parameters or thside design parameters are changed. And change the geometricphysical quantity which needs to be changed in the lateral model. It can not only guarantee the

26、nitial cause of the side wall design, but also guarantee the integrity of the side wall. It also helps designers avoid boredom and helps them save time,improve productivity, reduce work intensity, and give them more time to try and consider more options. There is considerable time to find the best d

27、esign from the solution. Through product design By modifying the dimension geometry simply, the streamlined design data model can be used to evaluate the optimal design scheme. You can uickly refer to and then come up with more design options for use.The main research directions and ideas of this th

28、esis include:1. study the fast and simple development steps of the side fenceand construct the theoretical model based on this idea.2. By synthesizing the opinions of the experts, the data model and the processing method of each model unit are improved.3. This paper studies the concrete application

29、of digital and analog engineering in the rapid development of side enclosure, and puts forward their realization methods.4. Explore the typical parts of the body's side circumference and create a typical partial database.5. Carry on the system development and method verification of the car body

30、side-girth rapid development system.6. Design dimension of side shell and related software design work.3. Historical retrospect and Development Direction of the side girth Design of New Energy vehiclesChina's auto industry returned to steady growth in 2017 after a decadeof rapid growth. In terms

31、 of long-term economic development, the impact of market consumer demand guided by national policies is relatively short-lived. After all, the rapid development of the automobile industry in recent years has contributed more to the growth of GDP in our country and has a huge impact on the economy. A

32、lthough the introduction of local purchase restrictions has had some impact on auto sales as a whole, the growth of the economy has not stopped the continued growth of the auto industry.First of all, as people's incomes continue to increase, China's per capita consumption level continues to

33、rise, there will be no sharp increase or decrease. Most of China still offers huge growth space for auto sales, with sales reaching 28.8789 million vehicles by 2017, an increase of 3.04 from a year earlier, according to statistics. Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing and other 46 first

34、-tier cities and some of the second-tier cities as many as 60 million cars. These cities account for 1/3 of the country's total car sales, and there is still plenty of room in the second-and-third-tier cities.Second, the advent of new energy vehicles has developed and vigorously promoted the dev

35、elopmen t of the automobile market. In order to meet the trend of the times, all the major automobile countries have made relevant positive policies . In China, the new energy vehicle market is positively influenced by the policies. As a result, it has made remarkable sales achievements, and at the

36、same time, a big economic country such as the United States has also adopted policies that are quite different from ours. The United States has increased the promotion of new energy vehicles by making great efforts to improve its infrastructure. Better integration of new energy vehicles into the U.S

37、. market will enable the American people to accept the integration of new energy vehicles.With the development of economic integration and the deepening of industrial division, the automobile industry of China, Brazil and the non-densely populated emerging countries is developing more rapidly. As a

38、result, the global auto market position is rising every day. Of course, India, Russia and other countries have also developed rapidly in recent years. Of course, all this cannot be separated from the emerging automobile market and become a new force in the global automobile industry. To enable inter

39、national auto giants and local auto companies to join the capacity of emerging auto markets.Second, the U.S., Japan, Germany and France, the old car power before the production has been significantly affected by the economic crisis. But overall levels remained relatively stable, with global car prod

40、uction returning to 2007 levels in 2010. Meanwhile, according to the China Association of Automobile Manufacturers, total auto production and sales in China increased rapidly in 2016, reaching a record high. Compared with the same period in 2015, the growth rate was 14.76 percent and 13.7percent res

41、pectively, up from 11.5 percent and 9.0 percent respectively in the same period last year.The global auto market is expected to continue to grow steadily in the coming years as demand from emerging market countries continues to grow, according to the 2017 forecast for global auto consumption by the

42、Chinese auto industry. Global car sales are expected to rise to 113.59 million in four years by 2022.4.ConclusionAt present, the research on the rapid design method of automobile body side girth is an important goal of modern body sid e design. The development of 3D modeling accelerates the design o

43、f aut omobile side circumference to a greater extent and improves the design efficiency. The design solution is optimized, so CAD will become the direction of automob ile design in the future. In the process of graduation design, people feel tha t catia s oftware is very effective in improving desig

44、n efficiency, design software is universal, not only in terms of car design, but it is necessary to build a modeling data mo del. More able to meet the needs of automotive design, improve automotive design In terms of parameterization, the quality of the side parts can be completed by modifying s om

45、e dimension parameters. In terms of the advantages of parameterization in computer aided design (CAD), Changing the side design from empirical design to data design, reducing the workload of design engineers, reducing the time of modeling task design, and applying more time to the innovation of body

46、 side structure. Improve the ability of independent technological innovation in China's automobile manufacturing industry.This paper makes a detailed analysis on the concept and structure optimization of the side wall design , but it is not enough in the analysis of the data model and the three

47、- dimensional model . It is hope d that the correspondin g deficiency can be found in the future work study , and the problem can be solved step by step .Car side design is a very complex project, in the design process of this paper, the application of theoretical knowledge is not well demonstrated,

48、 I hope that in the future work I can find relevant problems and gradually change. These are the ideas and feelings I got during the design of the sidewalk, as well as the overalldesign process and direction of thinking. However, as far as my personal ability is concerned, my understanding of some p

49、laces is not enough, and there arstill some missing points. I hope you can correct me in time, I will continue to improve in the future.5.References1 Xing Zhongwen, Fang Huasong, Xu Weili, et al.
