摘　　要：快换电池箱体是快换电池系统中的重要结构零部件。为缩短产品开发周期,降低开发成本,采用有限元仿真分析软件,以随机振动功率谱密度为激励载荷,在频域范围内研究电动乘用车快换电池箱体的疲劳特性,并进行寿命预测。通过随机振动台架试验,对有限元仿真分析结果进行验证,确认有限元分析方法在电动汽车动力电池系统开发中应用的可行性。The quick-change battery box is an important structural component of the quick-change battery system.In order to shorten the product development cycle and reduce the development cost,the finite element simulation analysis software was used to study the fatigue characteristics of the quick-change battery box of electric passenger car in the frequency domain with random vibration power spectral density as the excitation load,and make life prediction.Through the random vibration bench test,the finite element simulation analysis results were verified,and the feasibility of the finite element analysis method in the development of electric vehicle power battery system was confirmed.
