摘要
本文将火炮身管考虑为有限元梁单元,引入分析力学的拉格朗日方程推导系统动力学方程。提出了一种考虑身管柔性的刚-柔耦合多体系统动力学方法。
A multi-body gun dynamic mathod is given in this paper.Gun tube is consluered as finite beam elements as other components rigid bodies in this method. The coupled equations of rigid and fiexible bodies are established by using Lagrangian Equation;The results of numerical simulation are given as the sample of the method in this paper.
