汽车加速扭转共振问题的整改

为解决汽车加速扭转共振问题,探讨了某款柴油车在1 700 r/min左右产生的扭振和共鸣声的机理,可通过改变相关件的扭振频率及增加扭振阻尼来解决此问题.在没有双质量飞轮的情况下,最终通过调整离合器扭转减振器的刚度和阻尼,以及与传动轴挠性联轴器的组合运用,消除了该车型的扭振问题.结果表明,扭振是由系统共振引起,在扭振的源头采取对策才是最有效的方法.

Improvement on Vehicle Torque Vibration

This paper introduces diesel vehicle torque vibration and engine roar in the speed of 1700 rpm to improve vehicle torque vibration. Enhancing torque vibration frequency and decreasing torque vibration damping is the critical. Adjusting the rigidity and damping of shock absorber, combined with flexible coupling without dual mass flywheel （DMF） eliminated vehicle torque vibration. The system resonance creates vehicle torque vibration, making the countermeasures to eliminate the vibration during the period of initial torque vibration is the best way.
