【正文】 as the battery model. To ensure the safety,the pack’s strength and stiffness must meet the fundamental requirements. This paper mainly analyzed the strength and stiffness under different working conditons on the base of a finite element model. The rsult shows that and the corresponding stress and deformation graphs are structure of the battery pack is improved after analyzing the causes of the stress , the performance of the new model is pared with the original results show that the weight of the structure is reduced while the performance of the structure is improved, and the lightweight of the vehicle is realized.Keywords: power battery pack finite element method static structural analysis optimal design 引言 小型純電動(dòng)汽車(chē)作為我國(guó)新能源汽車(chē)產(chǎn)業(yè)化的戰(zhàn)略車(chē)型之一，得到了人們?cè)絹?lái)越多的關(guān)注。分析結(jié)果顯示，在垂直極限工況下，電池包底板的受力情況最為惡劣，因此對(duì)原有模型做出了改進(jìn)，改變底板加強(qiáng)筋的布置形式。純電動(dòng)汽車(chē)動(dòng)力電池包結(jié)構(gòu)靜力分析及優(yōu)化設(shè)計(jì)摘要： 動(dòng)力電池包作為純電動(dòng)汽車(chē)的唯一動(dòng)力源，承受著電池組等模塊的質(zhì)量，因此其強(qiáng)度、剛度必須滿足使用要求才可以保證行駛的安全性。在建立其有限元模型的基礎(chǔ)上，分析了電池包結(jié)構(gòu)在彎曲工況、緊急制動(dòng)工況、高速轉(zhuǎn)彎工況、垂直極限工況以及扭轉(zhuǎn)工況下的強(qiáng)度、剛度。經(jīng)過(guò)相同工況的模擬，發(fā)現(xiàn)在力學(xué)性能提升的基
