摘要
该文以转动刚体和其上固结的柔性梁组成的刚柔耦合系统为对象,利用子系统法研究了该系统的动力学问题并建立了耦合的动力学方程,此动力学方程考虑了“动力刚体”项。该文所提供的子系统法具有建模效率高,系统方程耦合度低等优点。文末给出的算例说明了方法的正确性。
The rigid-flexible coupling dynamics of a system consisting of a rotating hub and a flexible cantilever beam attached to the rotating hub is reported. The governing equations with the dynamic stiffening terms for this system are derived from the subsystem method reported in this paper. The subsystem method makes the modeling procedure more efficient and the coupling degrees of dynamic equations lower than that of the traditional method＇s. An example is given at the end of the paper to validate the presented method.
