摘　　要：为减少发动机振动对周围构件的不良影响,需要合理地选择发动机支座相对位置及减振器刚度。通过建立数学模型,讨论支座相对位置和减振器刚度满足一定关系时,发动机减振设计计算的简化方法,并给出相应的计算公式。设计发动机支撑结构时,利用此结论可得到较好的减振效果。Vibration damping design for engines. In order to minimize engine's vibration affecting components in the surrounding, you have to select relative position of the engine base and rigidity of the vibration damper accordingly. The text through construction of a mathematical model discusses how to simplify design and computation of the engine's vibration dampener and gives a corresponding computation formula given the mounting's relative position and the rigidity can satisfy a certain relationship, thus you could get a better vibration dampening result when utilising this conclusion in design of the engine's mounting.
