随着内燃机转速和性能的不断提高,使气缸内爆发压力有较大增加,并且使低谐次共振点的转速进入工作转速范围内,因而造成扭振幅值增加。降低扭振角的有效方法是安装一个强阻尼扭振减振器。对于橡胶减振器来说,增加转动惯量是可以提高减振效果的,但是,由于阻尼变化不明显,而且配置一个大型减振器,不仅对曲轴的横向振动不利,有时还会受到空间的限制。在这种情况下,需要提供一个尺寸比较
With the continuous improvement of internal combustion engine speed and performance, the outburst pressure in cylinders increases greatly, and the rotation speed of low harmonic resonance point enters the working speed range, thus resulting in the increase of torsional vibration amplitude. An effective way to reduce the torsional vibration angle is to install a strong damping torsional vibration damper. For the rubber shock absorber, increasing the moment of inertia can improve the vibration damping effect. However, due to the obvious change of the damping and the configuration of a large shock absorber, not only the lateral vibration of the crankshaft is not good but also the space is limited . In this case, you need to provide a size comparison
