The Development of Viscous Vibration Damper on Cummins ISLe Engine

介绍了康明斯ISLe柴油机硅油曲轴扭振减振器设计开发和研制过程。结果表明此减振器的减振性能优良,能够将曲轴前端的扭振振幅从0.43°降低到0.12°,满足康明斯设计标准;此减振器满足康明斯标准6循环工况发动机可靠性台架验证要求,为东风康明斯公司建立了曲轴扭振减振器国产化开发的工作流程。

This paper describes the process of design and research of the viscous vibration damper on Cummins ISLe engine. The result is as follows：This damper performance is so exeellent that the torsional vibration amplitude of engine freeend can be reduced from 0.43° to 0.12°and it meets the requirements of Cummins limited value less than 0.15°.The damper has passed Cummins standard Cycle 6 engine reliability test.The localization flow of vibration damperis built at Dongfeng Cummins.
