具有齿轮—绳索机械系统动态力学特性的研究方法

Study Method on Dynamic Behavior of Gear Rope Mechanical System

建立了具有齿轮—绳索机械系统的离散—连续动态力学模型；应用“动态子结构方法”并引入“虚约束”的概念得到了该类力学模型的动态响应；最后，应用该方法进行了实例计算，计算结果表明，其计算精度高于对应的离散动态力学模型。

In this paper the discrete continuous dynamic model of gear rope mechanical system is set up.The concepts of “dynamic substructure method”and “virtual constraint”are applied to get the dynamic response of this kind of mechanic model.And the results of calculated example have been indicated that the accuracy of discrete continuous dynamic model is higher than That of the correspondent discrete dynamic model.
