摘要
运用Ｋａｎｅ方法、有限元法及振动模态理论提出一种柔性多体动力学分析方法，推导出一组由系统刚体广义坐标和模态坐标表示的低阶多体动力学方程．其推导过程简捷，方程形式简单便于编程序计算．可有效地应用于自行火炮多体系统动力学及射击精度分析．
This paper presents a method of flexible multibody system dynamic analysis(FMSDA)by Kane method, FEM and vibration mode theory. The system dynamic equations which have a few degrees of freedom and are expressed as the functions of the system's rigid generalized coordinates and mode coordinates are obtained by this method. The equation form and the deduced processes are simple. The computer program can be compiled easily. The approach can be applied to the FMSDA and shooting accuracy analysis for vehicle selfpropelled gun effectively.
