Abstract: A tracking study on the durability of the instrument panel tube beam mounting points on the body of a certain commercial vehicle model during the reliability road test is conducted, and the body structure is optimized. The 3D model of the body and the finite element simulation model are established respectively by using 3D design software and HyperMesh software. Through the static strength and fatigue analysis of the body structure at the instrument panel tube beam mounting points, an improvement and optimization plan is proposed. After the simulation analysis results of the instrument panel tube beam mounting points of the optimized structure meet the requirements, the real vehicle verification is carried out. The research results show that through the static strength simulation analysis of the installation structure and the fatigue simulation analysis of the strengthened road spectrum, the durability problem of the key mounting points on the body can be solved, and a guiding method for the reliability structure design and performance achievement analysis of the key mounting points on the body is formed.
