摘　　要：发动机是整机的动力源,也是最主要的噪声和振动源。发动机在运转过程中产生的振动不但影响动力装置本身的结构及整个悬置系统的工作特性和寿命,而且还将引发噪声。因此,为了降低并衰减这种振动,通过采取减小发动机振动量级和衰减振动传递两种途径来探讨发动机振动对整机的影响,从而为有效降低发动机的振动与噪声提供依据。Engine is not only the power source, but also the most important source of noise and vibration for construction machinery. The vibration generated by Engine during its operation not only affects the characteristics of engine mounting system and structure safety, but will generate noise. Therefore, in order to reduce and damp this vibration, this paper takes two ways, that is to reduce engine vibration magnitude and attenuate this vibration by its transmission path, to discuss its influence, which can provide the basis to reduce the vibration and noise of the engine effectively.
