1、摘要 为了降低汽车传动系的振动，通常在传动系中串联一个弹性阻尼装置，它就 是装在离合器从动盘上的扭转减振器。 其弹性元件用来降低传动系前端的扭转刚 度，从而降低传动系扭转系统的某阶(通常为三阶)固有频率，改变系统的固有振 型，使之尽可能避开由发动机转矩主谐量激励引起的共振，其阻尼元件用来消耗 扭振能量，从而可有效降低传动系的共振载荷、非共振载荷及噪声。本文介绍了 扭转减振器的原理、工作过程及设计过程。并对其进行了简单的解释、分析。 关键词：离合器；扭转减振器；扭转弹簧；从动盘 Abstract In order to reduce the vibration of vehicle transm
