摘要
电动汽车的电驱系统集成了电机、减速器、差速器、驻车机构等,在工作过程中承受了各种复杂载荷,对其强度进行全面校核是非常必要的。建立了传动系统仿真分析模型和驻车机构多体动力学仿真分析模型,详细分析了电驱系统箱体在驱动工况、倒车工况、制动能量回收工况、驻车工况的受力。建立了电驱系统的有限元仿真分析模型,详细分析了箱体在上述各种工况的应力分布,并根据仿真分析结果对箱体进行了多轮优化,保证了箱体的可靠性。该仿真分析体系可用于指导箱体的结构设计。
Motor,transmission,differential,parking mechanism,etc.are integrated in the electric driving system of electric cars,which bears various types of complex loads.So it is necessary to analyze the strength of the entire electric driving system.The transmission simulation model and multi-body dynamics simulation model of the parking mechanism are built,and the loading of the electric driving housing is analyzed under different working conditions including driving,reversed driving,brake energy regeneration and parking.The finite element simulation models of the electric driving system are built,and the stress in the electric driving housing is analyzed.Based on the analysis results,the structures of the electric driving housing are optimized several times to ensure the reliability of the housing structure.This simulation evaluation system can be used to guide structure design of housings.
