The finite element model for a coach frame is built, then with the UG/NASTRAN solver, the authors cal-culate the bending stiffness and torsional stiffness. With the evaluation of the coach bodywork loading degree, they understand the contribution ration of a local structure in the vehicle load, which provides a reference for subsequent improvement body for the structure.
