摘要
基于柔性多体动力学理论 ,提出了变拓扑结构多体系统动力学建模方法。将系统约束分为基本约束和条件约束 ,研究运动相容性方程和铰接摩擦力的建模 ,对机动武器系统发射出筒过程进行动力学建模与仿真分析。
Based on flexible multibody dynamics,a dynamic modeling method on multibody systems with changing topologies is proposed.Classified the system constraints as basic constraints and variable constraints,the compatibility condition and the model of joint friction are studied.And then the dynamic model and the simulation analysis are given on the launching process during the missile flying away from the barrel in mobile missile system.The results of the research can be used in analysis and design of mobile missile systems.
