| Abstract: | Considering the factor of the nonlinear change of the suspension system＇s stiffness, the finite element model of the frame of the semi-trailer with concave-beam was established. The model with full loading was analyzed by ABAQUS software at a steady state, and stress analysis and calculation of the longitudinal beam were carried out by the method of classical mechanics. A free modal analysis of the frame was made by Bloek-lanezos method. The result shows that the frame strength and stiffness meet the design requirements. At the same time, torsion and local stiffness need to be strengthened. |
