Abstract：This paper analyzes the finite element stiffness variation of the rear door outer CAS(preliminary modeling surface)of the M01 model based on grid deformation technology.The existing finite element model of the rear door of the old model is deformed using the MeshWorks software to accurately obtain the finite ele-ment model of the rear door outer CAS.The bending stiffness and lateral stiffness of the rear door before and after deformation are calculated respectively,the reasons for the stiffness change are analyzed,and the conclu-sion is drawn that using MeshWorks software can quickly establish a new finite element model based on the ex-isting grid,and the overall bending degree of the rear door will decrease,which will significantly reduce the bending stiffness.
