Abstract : A leaf spring and lubricating oil damper design method is introduced. Firstly, the most impor-tant order of the shafts torsional vibration is controlled by using simplified model through optimal frequen-cy ration and optimal damping ratio in dynamic vibration absorbing theory, which could determine the vi-bration-reduction parameters preliminarily. Then, the characteristic parameters are further adjusted through the calculation of shafts torsional vibration by using detailed model, with the aim to realize opti-mal vibration control. After that, the structure design is carried out based on the parameters design re-sults, and the structure design method about the two characteristic parameters, torsional stiffness and damping coefficient, is introduced mainly. The design verification was conducted at last. This method was applied to the damper design of HND 622V20CR diesel, and the results show that the leaf spring and lubricating oil damper boasts much better vibration reduction effect then the original one.

0引言
簧片滑油型扭振减振器安装在柴油机自由端，与柴油机曲轴一起运转。对于柴油机轴系扭转振动控制来说，簧片滑油型扭振器具有调节轴系扭振频率、减小扭振振幅的功能，并且具有阻尼大、运行
可靠、寿命长等优点。随着柴油机单缸功率不断提高，轴系也日益复杂化，随之带来扭振性能恶化。目前，簧片滑油型扭振减振器已在国外高、中、低速柴油机上广泛使用，其设计制造技术被盖斯林格公司垒断。随着我国各大柴油机厂、相关科研院所柴油机自主研制项目的开展，扭振减振器的设计技
