摘要: 本文把中篇建立的间隙铰模型引入多体系统动力学分析中,得到了一种处理含间隙多体系统动力学问题的一般方法。应用这种方法对机动武器的发射过程进行了原理性的仿真,验证了前面建立的碰撞模型和间隙模型,并分析了间隙对导弹运动状态的影响。导弹发射过程具有变拓扑的特点,本文方法提供了一种处理这类问题的思路。

Abstract: A general method is derived for the dynamic analysis of multi-body systems with clearance by applying the clearance models gained in Part II . Elementary simulations are performed using this method on the dynamic characteristics in the launching phase of mobile missile, which verify the impact model and the clearance model established m Part Ⅰ and Part II . The effects of clearances on the dynamic behavior of missile are also discussed. In addition,the system topological structure changes during the launching phase, thus the method in tins paper provides a solution for this kind of problems.

Key words: mechanics , clearance , multi-body dynamics , simulation , launching of missile
