| Abstract: | This paper deals with optimal design of a vehicle frame. The unevenness of the dynamic stresses in vehicle frame is taken as objective function and the size of cross -section as design variable. The data of road spectral density is used to calculate the stresses of the vehicle frame. For achieving fast and accurate calculation for the objective function, the mode-acceleration method, the perturbation method and the variable error polyhedron method are introduced and theoretical calculation and experimental study are carried out. |
