38、操作方便性、上下車方便性等作為主要因素考慮。在車身總布置設(shè)計(jì)中,應(yīng)該充分考慮人—車—路系統(tǒng)的綜合優(yōu)化。合理的人機(jī)工程布置設(shè)計(jì),不僅關(guān)系到有效的利用車內(nèi)空間及提高乘坐舒適性,會(huì)影響車內(nèi)、外部造型和整車尺寸參數(shù),進(jìn)一步會(huì)影響整車性能和市場(chǎng)競(jìng)爭(zhēng)力。人體工程設(shè)計(jì)的基本要求是操縱方便和舒適性,即盡最大可能的滿足不同身材和姿勢(shì)的駕駛者對(duì)操縱件的手足伸及性與姿勢(shì)舒適性以及視野性的要求。人機(jī)工程設(shè)計(jì)主要借助于SAE的方法和工具。在汽車設(shè)計(jì)中的應(yīng)用有如下

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(jì)方法在車身設(shè)計(jì)中的應(yīng)用。這種方法(傳統(tǒng)的車身CAD方法)的一個(gè)主要工作是利用計(jì)算機(jī)輔助幾何設(shè)計(jì)(CAGD)方法來(lái)進(jìn)行車身幾何造型設(shè)計(jì),即要在計(jì)算機(jī)上建立一個(gè)車身表面模型以取代傳統(tǒng)設(shè)計(jì)中的三維實(shí)體模型。但無(wú)論是傳統(tǒng)的手工設(shè)計(jì)方法,還是傳統(tǒng)的車身CAD設(shè)計(jì)方法,都免不了進(jìn)行車身效果圖繪制、車身油泥實(shí)物型模型制作等步聚,這就大大增加了設(shè)計(jì)開(kāi)發(fā)的周期和成本。</p>&l

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