本文采用基于凯恩方程和休斯敦方法的柔性多体动力学理论,着重研究了柔性多体系统的动力刚化现象。以板类和桁架类零件为典型,阐述其理论体系,开发通用分析程序,开展数字仿真研究,并给出上述典型零件的计算结果。
In this paper, a flexible multi-body dynamics theory based on the Kane’s equation and the Houston method is used to study the dynamic rigidization of a flexible multi-body system. Taking the plate and truss parts as examples, the theoretical system is elaborated, the general analysis program is developed, the digital simulation is carried out, and the calculation results of the above typical parts are given.
