Research on Static Analysis of the Vehicle Frame Based on Finite Element Analysis

Aiming at the problem of complex transfer relationship of force and deformation in the vehicle frame, the finite element method is used to study the displacement and stress distribution. The vehicle model is built in the three-dimensional software. The vehicle is simplified to ensure the smooth progress of the calculation. The three-dimensional model of the simplified vehicle is imported into the finite element analysis software. A finite element analysis vehicle model is built. The displacement and stress distribution of the frame are analyzed when the vehicle is under the torsional condition, the braking condition and the turning condition. The analysis results show that the frame can meet the design requirements under the three typical working conditions. The results can lay solid foundations for the relevant experiments, dynamic analysis and calculation as well as the structure optimization design for the vehicle frame.
