摘　　要：发动机悬置的解耦率和隔振率是汽车动力总成设计的两个主要性能指标。通过iSIGHT软件集成Matlab与ADAMS,建立综合考虑解耦率和隔振率的数学模型,利用非支配解排序遗传算法对悬置系统的性能参数进行多目标优化。实车测试结果验证了该方法的可行性。Energy decoupling rate and vibration isolation rate of engine mounts are the two important performanee indicators in designing vehicle powertrain assembly. Through integrating Matlab and ADAMS by software iSIGHT, a math model concurrently considering both energy decoupling rate and vibration isolation rate is built, and a multi-objective optimization on the performance parameters of mounting system is conducted by using non-dominated sorting genetic algorithm. The results of real vehicle test verify the feasibility of the method proposed.
