摘　　要：以商用车传动轴为研究对象,基于Optistruct有限元分析软件对其进行力学仿真分析,考察在最大扭矩作用下传动轴上各部件的应力与位移分布情况,校核其强度和刚度.结合传动轴的应力分布和制造工艺要求,对传动轴部件开展轻量化设计.结果表明:利用仿真分析手段可以快速得到传动轴总成的传力路径,引入制造工艺要求进行轻量化设计后的部件不仅满足制造加工要求,而且应力分布更均匀.传动轴整体结构从原始23.8 kg减少为16.8 kg,减质量占比30%.该轻量化设计方法可在满足传动轴结构强度情况下快速实现减重目标.The transmission shaft of commercial vehicles was taken as the research object,and mechanical simulation analysis was conducted based on the finite element analysis software of Optistruct to investigate the stress and displacement distribution of various components on the transmission shaft under maximum torque,and to verify its strength and stiffness.In addition,based on the stress distribution and manufacturing process requirements of the transmission shaft,lightweight design was carried out for the transmission shaft components.The research results indicated that using simulation analysis methods can quickly obtain the force transmission path of the transmission shaft assembly,and introducing manufacturing process requirements for lightweight design not only met the manufacturing requirements,but also had a more uniform stress distribution.The overall structure of the transmission shaft was reduced from 23.8 kg to 16.8 kg,with a weight reduction of 30%.The lightweight design method described in this article can quickly achieve weight reduction goals while meeting the structural strength of the transmission shaft.
