| 摘 要： | 针对某车动力总成悬置系统固有频率偏高和振动耦合严重的问题,建立了该车动力总成悬置系统6自由度模型,并对悬置元件的主刚度参数进行了灵敏度分析.以分析找出的少量敏感参数为设计变量,结合振动解耦和固有频率匹配理论,对该悬置系统参数进行了优化,并对优化前后的动力总成悬置系统进行了台架试验.结果表明,优化后的悬置系统隔振能力有了...

| Abstract: | For tackling the issue of high natural frequencies and severe vibration coupling in the powertrian mounting system of a vehicle,a 6 DOFs model for that mounting system is built,and a sensitivity analysis for the principal stiffness parameters of mounting components is performed.Taking a few sensitive parameters found by above analysis as design variables and combining with the theories of vibration decoupling and natural frequency matching,an optimization on mounting system parameters is conducted and the b... |
