摘　　要：我们简述了发动机产生振动的原理,分析了发动机对车身振动的传递特性。以某型号直列四缸发动机为例,建立了发动机悬置振动系统模型,通过研究降低发动机对车身振动最有效的措施是调整车身联结点的刚度。为实现对发动机振动的控制,建立了发动机振动控制系统模型,研究表明主动控制技术可以较好地抑制发动机对车身的振动。This paper describes the principle of engine vibration, and analyzes the transmission characteristics of engine to body vibration, Taking certain model inline four-cylinder engine as an example, the engine mount vibration system model was established. Through the research, the most effective measures to reduce engine for vehicle vibration is to adjust join points ^ stiffness of body. In order to control the vibration of engine, a model of engine vibration control system is established. The research shows that the active control technology can restrain the vibration of the engine.
