摘　　要：简述了发动机导致车内噪声的两种方式,即振动传递方式和辐射方式。基于发动机的激励特点和传递方式论述了发动机对整车振动噪声的影响规律及控制措施。基于动力总成隔振悬置需要满足的诸多冲突因素和约束条件,论述了汽车动力总成隔振设计难点,并阐述了被动式悬置改进技术。The vibration transmission and radiation ways that induced noise in cab were introduced in this paper. The influence rule and control methods of engine on vehicle＇s vibration and noise were analyzed based on the engine excitation characteristics and the different transmission modes.The difficulties in automotive powertrain vibration isolation mounting design and the improved technologies of passive mounting were discussed based on the conflicting demands and the constraint conditions.

关 键 词：动力总成 隔振 被动式悬置 设计
