摘　　要：本文以一实际的三缸车用发动机为例 ,经计算分析与实测 ,采用过量平衡法改善其平衡特性以及对该机的支承位置和减振器刚度进行调整后 ,使该机组振动烈度大大降低 ,达到了预期效果。In this article,the vibration of a three cylinder engine equipped on cars is discussed.After the theoretical analysis and practical measurements,we improved the balance characteristics according to rule of over balancing.Meanwhile,the position of supporting and the rigidity of the shock absorber are adjusted.As a result,the vibration intensity of this set is greatly reduced and has reached the anticipant level.
