Test and Simulation Study on Stiffness of Automotive Door

Automotive door must have adequate stiffness as the important component of an automobile. In this paper, firstly, bending stiffness, torsional stiffness and sinking stiffness of an automotive door were simulated, got the deformation curves of the door in the three conditions. Then an experiment was used to verify the result of finite element analysis. These two methods complemented each other. The stiffness of the door was studied and analyzed by two methods, provided a reference for the improvement of the door.
