摘　　要：对SGA92150型半挂车车架的总体布置、纵梁、横梁、纵梁与横梁的连接等进行了设计.利用有限元软件Ansys Workbench对车架进行应力和变形计算,利用Matlab软件采用传统方法对纵梁进行受力分析和应力计算.结果表明车架强度和刚度均满足要求.An SGA92150 semi-trailer frame＇s layout, longitudinal girders, crossgirders and joints were designed. The stress and deformation of the frame were calculated by using Ansys Workbench software with advanced method, and the force analysis and stress calculation of the longitudinal girder were carried out by using Matlab software with conventional method. The results show that the frame＇s strength and stiffness are enough to meet the design requirements.
