摘　　要：汽车的NVH性能决定了汽车的内在品质,汽车的动力总成悬置系统设计的优劣对汽车的NVH性能有重要的影响。针对某混合动力客车行驶时出现的NVH状况,通过建立客车动力总成悬置系统的动力学模型,对其悬置系统进行理论分析。基于能量法解耦理论,分析了悬置刚度、安装位置等参量对动力总成悬置系统的影响规律,并进行了优化设计。通过ADAMS建立仿真模型从时域与频域方面进行悬置系统性能分析,并结合整车振动试验测试对比,验证了优化设计的合理性及有效性,改善了客车动力总成悬置系统的隔振性能。The NVH performance of vehicles determine the intrinsic quality of the automobile, the quality of the powertrain mounting system design has an important impact on the Automobile NVH performance. Based on the NVH status of a Hybrid Electric bus, the mechanical model of the powertrain mounting system is established, and its suspension system is analyzed. Based on the decoupling theory of energy method, the influence of the parameters of the suspension stiffness and installation position on the powertrain mounting system is analyzed, and the optimal design of the system is also analyzed. The simulation model is established by ADAMS and the performance of suspension system in time domain and frequency domain is analysised,combined with the vehicle vibration test and comparisonand, the rationality and validity of the optimized design are verified and the vibration isolation performance of the bus powertrain mounting system is improved.
