摘　　要：基于对发动机进行动力学分析基础上,设计发动机设计双轴平衡机构,达到减弱或消除某次往复惯性力的目的以及尽可能的减小本次倾覆力矩。对比安装使用所设计双轴平衡机构前后振动情况,使用双轴平衡极大地改善了该此类发动机的振动特性,完全平衡了某次往复惯性力,最大限度地消减了此次侧倾力矩。本方法的研究对该类型发动机设计及减振设计都具有很强的实用价值和指导意义。In this article,the biaxial balance mechanism is designed on the basis of the kinetic analysis of the engine,and the purpose of weaken or elimination the reciprocating inertia force is got and also reduced the overturning moment as much as possible.Comparing with the vibration conditions that without the biaxial balance mechanism,using a biaxial balance greatly improve the vibration characteristics of all such engine,the reciprocating inertia force completely is balanced and the overturning moment is reduced.This method has a strong value and practical significance for engine design and vibration design.
