摘　　要：通过建立某V型船用柴油机的轴系扭振当量系统模型,进行曲轴扭转振动的计算分析;根据分析结果对该船用柴油机进行硅油减振器匹配设计,以保证曲轴自由端共振振幅及轴段扭振应力低于许用值,同时硅油减振器的散热能力符合要求。扭振测试验证表明:所匹配设计的减振器满足规范和设备安全运行的要求。The equivalent system model of crankshaft torsional vibration for a V type marine diesel engine was built for calculation and analysis. Matching design of viscous damper for the marine diesel engine was carried out according to the analysis results to ensure that resonance amplitude on the free end of crank- shaft and torsional vibration stress on the shaft section were below allowable values, meanwhile the heat dissipation capability of viscous damper could conform to the requirements. And finally, the matched tor- sional vibration damper was verified by the test to meet the rules and requirements for safe operation.
