摘　　要：针对实际应用中S195柴油机工作时的噪声大,系统稳定性差等问题。本文基于含间隙曲柄滑块机构的振动特性的分析,在ADAMS/Vibration中建立振动分析模型,添加三种不同的激振力,进行模态和强迫振动分析,进而得到系统的各阶模态的固有频率、模态主振型及频率响应信息,以此作为曲柄滑块机构设计参数,并将参数应用于S195柴油机工作的性能测试实验中,为S195柴油机工作性能的优化提供有力的理论依据。In practical application,large noise,poor system stability and other issuesare existedinS195 diesel engine.In this paper,based on the analysis of the vibration characteristics of the crank-slier mechanism with clearance,the vibration analysis model isestablished in the ADAMS/Vibration.The modal main mode and the frequency response curve of the system are obtained by adding three different forces,having modal and forced vibration analysis.It is a parameter for the design of the organization,providing a theoretical basis for optimal design of diesel engine.
