3、曲率等。1.1.2.1.3繪制概念草圖步驟在繪制概念草圖之前，是在已經(jīng)了解項(xiàng)目定位、對項(xiàng)目有了初步策劃方案，并且對競品車或?qū)?biāo)車進(jìn)行了大量分析的前提下開始繪制。通常，概念草圖的繪制需要如下步驟：（ 1）首先建立車身坐標(biāo)系，“國標(biāo)”定義的“整車坐標(biāo)系”。通過空載或設(shè)計(jì)載荷時車輪中心（左、右前輪和左、右后輪）及地板門檻縱平面來確定整車坐標(biāo)系。然后擺放車姿，如圖1-2所示。圖 1-2（ 2）確定踏板和踵點(diǎn)位置，如圖1-3 所示。踏板組后踵點(diǎn)前踵點(diǎn)圖 1-3（ 3）先確定前排H點(diǎn)位置，再確定后排H 點(diǎn)位置，如圖1-4 所示。- 2 -總體所設(shè)計(jì)手冊總布置圖前排 H點(diǎn)后排 H點(diǎn)圖 1-4（ 4）確定方向

4、盤位置，如圖1-5 所示。方向盤各種位置圖 1-5（ 5）用人機(jī)工程軟件校核H 點(diǎn)、踵點(diǎn)和方向盤的位置關(guān)系，并進(jìn)行優(yōu)化。根據(jù)優(yōu)化后的結(jié)果，對駕駛員和后排乘客進(jìn)行坐姿擺放，如圖1-6 所示。- 3 -總體所設(shè)計(jì)手冊總布置圖圖 1-6（ 6）確定發(fā)動機(jī)和發(fā)動機(jī)蓋板的位置，定義C點(diǎn)位置，如圖1-7 所示。圖 1-7（ 7）根據(jù)頭部空間的需要，確定頂棚的位置，如果必要參照對標(biāo)車確定，如圖1-8 所示。頂棚最高位置限制面圖 1-8- 4 -總體所設(shè)計(jì)手冊總布置圖（ 8）按照法規(guī)確定保險杠的位置，如圖1-9 所示。前保險杠位置后保險杠位置圖 1-9（ 9）確定體現(xiàn)車身主要尺寸的輪廓線或限制面，如圖1-10

5、 所示。圖 1-10（ 10）確定前后風(fēng)擋玻璃的形狀和位置，如圖1-11 所示。圖 1-11（ 11）前方視野校核，根據(jù)眼點(diǎn)位置，風(fēng)擋玻璃開口尺寸，發(fā)動機(jī)蓋板位置，校核前方視野，如圖 1-12 所示。- 5 -總體所設(shè)計(jì)手冊總布置圖圖 1-12（ 12）繪制二維正視圖，如圖1-13 所示。圖 1-13（ 13）繪制二維側(cè)視圖，如圖1-14 所示。- 6 -總體所設(shè)計(jì)手冊總布置圖圖 1-14（ 14）繪制二維俯視圖，如圖1-15 所示。圖 1-151.1.2.1.4概念草圖輸出繪制完成的第一版總布置圖 - 概念草圖連同車型描述表、 工程設(shè)計(jì)目標(biāo)或者儲物空間定義等文件一同輸出造型，指導(dǎo)造型設(shè)計(jì)。1
