汽车中双质量飞轮的研究与分析

Research and Analysis of Double Mass Flywheel in Automobile

汽车传动系扭振的激振源较多,发动机曲轴转矩波动是扭振的主要振源。为应对这一问题,在汽车中配备了双质量飞轮。介绍了双质量飞轮的发展历史、基本结构和减振原理,分析了双质量飞轮的优点。论述了我国双质量飞轮的研发现状,同时对其发展前景进行了展望。

There are many shock excitation sources for torsional oscillation of automobile transmission system, and the torque fluctuation of engine crankshaft is the main vibration source of torsional oscillation. In response to this issue, a dual mass flywheel is equipped in the automobile. The development history, basic structure and vibration reduction principle of the dual mass flywheel were introduced, and the advantages of the dual mass flywheel were analyzed. The R & D status of dual mass flywheel in China was discussed and its development trend was prospected.
