摘　　要：分别采用Mooney-Rivlin,Odgen和Yeoh橡胶材料本构模型对永磁同步直驱系统用弹性联轴器进行有限元建模和径向刚度仿真计算,并将仿真计算结果与试验结果进行对比。分析得出,采用Mooney-Rivlin和Odgen模型得到的弹性联轴器径向刚度与试验值偏差较大,采用能够模拟大变形的Yeoh模型得到的弹性联轴器径向刚度与试验值偏差较小,Yeoh模型适合用于弹性联轴器及同类产品进行力学性能分析。The rubber material constitutive models,Mooney Rivlin,Odgen and Yeoh models,were applied to study the properties of the resilient coupling used in the permanent magnet synchronous direct drive system,the radial stiffness of the resilient coupling was calculated,and the simulation results were compared with the test results.The analysis results showed that the radial stiffness of the resilient coupling obtained by Mooney Rivlin and Odgen models deviated greatly from the testing results,while the radial stiffness obtained by Yeoh model which could simulate large deformation had only small deviation.Yeoh model was more suitable for the mechanical property analysis of the resilient coupling and similar products.
