齿式橡胶联轴器动力力学建模与分析

以一款齿式橡胶联轴器为研究对象，首先采用有限元软件对齿式橡胶联轴器的弹性元件进行动力分析，得到橡胶元件的恢复力 位移数据，其次运用拟合分解法建立了弹性联轴器恢复力的数学模型，其刚度系数和阻尼系数是关于位移振幅和频率的函数。最后分析了联轴器的幅频特性和扭矩传递系数，结果表明，弹性橡胶联轴器在有效传递扭矩的同时，表现出软弹簧的非线性特性。

Dynamic Modeling and Analysis of Gear Rubber Coupling

This article focuses on a gear rubber coupling. Firstly, the rubber elements of the coupling are analyzed using the finite elements method to get the restoring force displacement data. Then a mathematical function against displacement is built using a trace method in which the restoring force is decomposed into a spring force and a damp force. Finally, the amplitude frequency characteristic and the torque transmission of the gear rubber coupling are analyzed, and the result shows that the coupling not only transmits torque efficiently but also presents characteristics of a soft spring.
