Geislinger联轴器扭振研究

Study of torsional vibration for geislinger coupling

从单自由度扭振系统出发,研究了Geislinger联轴器的动态特性。发现当Geislinger联轴器在承受波动转矩时,其刚度和阻尼会随振动频率的变化而变化,动刚度会使系统固有频率产生偏移。进一步研究表明,动态阻尼对振幅值的影响较大,而对频率偏移基本没有影响。同时,通过对联轴器扭振方程的求解,解算出联轴器的不同阶次的固有频率。

The article studied the dynamic feature of Geislinger Coupling from the point of view of building single-mode torsional vibration system,finding that when the Geislinger Coupling was subject to the fluctuant torsion,the stiffness and damping would change as vibrational frequency of the system changed,and the dynamic stiffness made the free frequency of the system deviate. The further study showed that dynamic damping had greater effect on the amplitude of the system and almost no effect on the deviation of the frequency. At the same time ,through solving the torsional vibration equation of the coupling,the free frequency of different steps of the coupling was worked out.
