Structure design and strength and stiffness analysis of an SGA92150 semi-trailer frame

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.
