摘要
为使我校研制的警务电动汽车、旅游观光车等车型多样化,在微型电动汽车基础上,设计某型号中型电动汽车车架结构。首先在仿真软件ANSYS Workbench中建立中型电动汽车车架有限元模型,其次对电动汽车车架进行预应力模态分析,最后根据分析结果提出改进方案,利用ANSYS Workbench的DOE优化模块确定角钢型号,进行多目标优化。优化后结果不仅改善了车架动态性能,而且将其质量减轻,在保证中型电动汽车结构稳定基础上,实现了车架轻量化设计。
In order to make the school pohce electric vehicles, sightseeing vehicles and other models diversified, a frame structure for a electric vehicle is designed based on the micro electric vehicles. Firstly, the finite element model of the medium electric vehicle is created in the ANSYS Workbench simulation software. Secondly, prestress modal analysis is performed on the electric vehicle frame. At last, the improved scheme is proposed according to the analysis result, and the DOE optimization module of ANSYS Workbench is applied to identify the model. The optimized result shows that not only the dynamic performance of the frame is improved, but also the weight of the frame is reduced. On the basis of ensuring the structural stability, the lightweight design of the frame is achieved on the medium electric vehicle.
