45、，高速圖形終端和工作站的出現(xiàn)，引進(jìn)了CAD/CAM等現(xiàn)代設(shè)計方法在車身設(shè)計中的應(yīng)用。這種方法（傳統(tǒng)的車身CAD方法）的一個主要工作是利用計算機(jī)輔助幾何設(shè)計(CAGD)方法來進(jìn)行車身幾何造型設(shè)計，即要在計算機(jī)上建立一個車身表面模型以取代傳統(tǒng)設(shè)計中的三維實體模型。但無論是傳統(tǒng)的手工設(shè)計方法，還是傳統(tǒng)的車身CAD設(shè)計方法，都免不了進(jìn)行車身效果圖繪制、車身油泥實物型模型制作等步聚，這就大大增加了設(shè)計開發(fā)的周期和成本。</p>&l

46、t;p>　　因此，建立一種汽車車身計算機(jī)輔助設(shè)計和分析的方法——虛擬樣機(jī)設(shè)計方法意義重大。汽車車身采用虛擬樣機(jī)的設(shè)計方法，是一種革新產(chǎn)品開發(fā)過程、縮短周期降低成本、改進(jìn)產(chǎn)品設(shè)計質(zhì)量、提高產(chǎn)品開發(fā)效率的有效途徑。采用虛擬樣機(jī)設(shè)計方法，在制造第一臺物理樣機(jī)之前，利用計算機(jī)模型可以仿真測試各種不同的設(shè)計方案，不必浪費(fèi)制造物理樣機(jī)所需的時間與經(jīng)費(fèi)，可以獲得較優(yōu)的乃至最優(yōu)的設(shè)計方案；同時可以在計算機(jī)上方便地確定、修改設(shè)計缺陷，逐步優(yōu)化設(shè)計方
