| Abstract: | By using optimal design together with finite element analysis,the dynamic resonant frequencies of motorcycle structure have been modified in order to avoid serious resonant vibration probems in the range of engine speed.The result shows that the structural dynamic property is one of the constraints that affect the feasible region of optimization and the optimized results. |
