摘　　要：为减轻蓄电池框架车自重,以使车辆有更好的续航能力,本研究对蓄电池框架车进行了系统分析,对整车受力进行了理论计算,并建立了动力学仿真虚拟样机,进行了6种工况的仿真分析,计算与仿真结果相近。然后,选取关键元部件受力最大的满载过坑工况作为静力学分析基础,在有限元分析软件中对关键零部件进行静力学分析,将动力学获取的受力范围,合理地添加在模型中,进行了铰接销轴与摆动梁的静力学强度校核,结果均小于其许用应力,满足使用要求。最后对铰接销轴与摆动梁进行可靠性定量分析,结果均满足失效概率为1×10^(-5)的指标要求。In order to reduce the weight of the battery frame vehicle and improve its endurance,force on the whole vehicle force was theoretically calculated,and a virtual prototype of dynamics simulation was built and simulated for six working conditions,the calculation and simulation results were similar,which verified the accuracy of the prototype.And the full-load over-pit working condition with the greatest force on key element parts was selected as the basis of static analysis.The static analysis of the key components was carried out with the finite element analysis software,and the forces obtained from the dynamics were added to the model in a reasonable way,and the static strength checks of the hinge pin and swing beam were carried out,and the results were within the range of permissible stress.The quantitative reliability analysis of the articulated pin and the oscillating beam was carried out,and they both met the requirement of 1×10^(-5) failure probability.
