| Abstract: | In this paper, we establish a FEA model to calculate the torsional stiffness and do the modal analysis of the EQ6111LH bus body. The torsional stiffness and the first torsion mode frequency are selected to do the sensitivity analysis. Then according to the results of the sensitivity analysis, the appropriate design variables are chosen to perform the optimization for the torsinal stiffness of the bus. And discrete design variables are used in the process of optimization. |
