總體設(shè)計(jì)手冊(cè)-總布置圖

1.1 總布置圖繪制1.1.1 意義根據(jù)新產(chǎn)品規(guī)劃和概念設(shè)計(jì)確定車身總布置方案，然后再繪制總布置草圖，然后開始進(jìn)一步的 造型設(shè)計(jì)。其中整車總布置草圖的繪制對(duì)后期的開發(fā)設(shè)計(jì)起到依據(jù)和指導(dǎo)作用。1.1.2 總布置草圖的繪制第一版總布置圖-概念草圖1.1.2.1.1

總布置草圖內(nèi)容草圖階段的總布置圖，主要是對(duì)造型的輸入，體現(xiàn)總布置的基本硬點(diǎn)參數(shù)，其中最重要的是H點(diǎn)的位置，H點(diǎn)是整車的設(shè)計(jì)參考點(diǎn)，必須在早期準(zhǔn)確地確定，一旦更改將對(duì)整個(gè)前期的布置設(shè)計(jì) 及項(xiàng)目進(jìn)度產(chǎn)生重大的影響。在草圖階段的總布置圖中，主要體現(xiàn)如下內(nèi)容：1、H點(diǎn)坐標(biāo)，人機(jī)內(nèi)部空間等相關(guān)參數(shù)；2、整車外廓尺寸，包括長、寬、高、輪距、軸距、前懸、后懸；3、法規(guī)要求及設(shè)計(jì)目標(biāo)；4、COW件的狀態(tài)；5.三種載荷狀態(tài)的地面線；6、各種限制面；7、其他，如車門形式、玻璃曲率等。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(duì)項(xiàng)目有了初步策劃方案，并且對(duì)競品車或?qū)?標(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：1-2(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(shí)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 所示。圖1-2(2)確定踏板和踵點(diǎn)位置，如圖 1-3所示。(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。后排H前排H圖1-5圖1-4(4)確定方向盤位置，如圖 1-5所示。(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,方向盤各種位置對(duì)駕駛員和后排乘客進(jìn)彳T坐姿擺放，如圖1-6所示。圖1-6(6)確定發(fā)動(dòng)機(jī)和發(fā)動(dòng)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(duì)標(biāo)車確定，如圖1-8所示。圖1-8(8)按照法規(guī)確定保險(xiǎn)杠的位置，如圖 1-9所示。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(dòng)機(jī)蓋板位置，校核前方視野, 如圖1-12所示。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。圖 1-151.1.2.1.4
