摘要
在摩托车车架的优化设计中 ,结合有限元计算 ,调整结构自振频率 ,可有效减少常用转速下因共振而带来的问题 ,分析表明 ,结构动态特性作为摩托车结构优化设计的约束条件之一 ,影响最优化约束可行域的大小 ,从而影响最优化结果。
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.
