十字环槽式双万向联轴器中间轴动力学分析

Dynamic Analysis of Middle Axis of Double Ring-and-trunnion Universal Joint

对于十字环槽式双万向联轴器,其各个部件的受力比较复杂,尤其中间轴受到的是随时间变化的载荷,其动态性能的优劣会直接影响在高速旋转下的性能和寿命。本文应用Pro/E、ANSYS等软件,对十字环槽式双万向联轴器中间轴进行了模态、临界转速、动响应等动力学有限元分析,计算分析结果为十字环槽式双万向联轴器的设计制造和应用提供了必要的依据。

The performance and life of a double ring-and-trunnion under high-speed turn is affected directly by its dynamic property,because the forces applied to its parts are very complex and especially the load applied to the middle axis is variable.Through the finite element method,the mode,critically rotative velocity and dynamic response of the middle axis of a double ring-and-trunnion universal joint in ProE and ANSYS are analyzed.The result provides sufficient basis for the design,production and application of double ring-and-trunnion universal joint.
