摘　　要：首先以某小型电动货车的车架和电池包作为分析对象,运用CATIA V5R21建模软件和ANSYS 2021R2分析软件建立有限元模型。然后进行静力学预分析,得出结果后设置安全系数,并分别对有限元模型进行拓扑优化;在得出拓扑优化结果后,按照得出的有限元模型形状在CATIAV5R21中对有限元模型进行修改,得出新的有限元模型。最后重复之前的全部步骤,得出拓扑优化后有限元模型的安全系数,进行拓扑优化轻量化设计可行性分析,直到车架和电池包符合电动货车安全性的要求。经过本次轻量化设计与分析,车架整体自重降低了43.842kg,大约12.7%,电池包整体自重降低了29.87kg,大约19.9%。Firstly,the frame and battery pack of a small electric vans are used as the analysis objects,and the CATIA V5R21 modeling software and ANSYS 2021R2 analysis software are used to build a finite element model.Secondly,the static pre-analysis was carried out,and the safety factor was set after the results were obtained,and the topology optimization of the finite element models was carried out respectively.After the topology optimization results are obtained,the model is modified in CATIA V5R21 according to the resulting model shape to obtain a new finite element model.Finally,all the steps carried out before will be repeated to obtain the safety factor of the finite element model after topology optimization,and the feasibility analysis of topology optimization lightweight design will be carried out,until the frame and battery pack meet the safety requirements of electric vans.After this lightweight design,the overall weight of the frame has been reduced by 43.842 kg,about 12.7%,and the overall weight of the battery pack has been reduced by 29.87 kg,about 19.9%.
