半挂车90#牵引座结构强度分析

Structural Strength Analysis of 90#Traction Seat of Semi-trailer

采用有限元分析法对90#牵引座进行了强度分析,在软件中模拟给定载荷的工况环境,研究牵引座的应力和变形分布状况。模拟结果表明,牵引座最大等效应力位于后加强筋接触区域,最大等效应力值为318.55 MPa;最大变形位于壳体后顶部,最大变形值为0.7254 mm。将该分析结果与试验数据对比,对比结果表明分析结果真实可靠,为牵引座的优化设计提供了理论依据。

The strength analysis of 90#traction seat was carried out by finite element analysis method,and the stress and deformation distribution of traction seat were studied by simulating the working condition environment of given load in the software.The simulation results show that the maximum equivalent stress of the traction seat is located in the contact area of the rear reinforcement,and the maximum equivalent stress is 318.55 MPa.The maximum deformation is located at the back top of the shell,and the maximum deformation value is 0.7254 mm.The analysis results are compared with the experimental data,and the comparison results show that the analysis results are true and reliable,which provides a theoretical basis for the optimal design of traction seat.
