摘要
在对若干模型比较的基础上 ,提出一种新的含摩擦碰撞模型。该方法将一些基本关系设定为由试验或理论估算得到的一般函数的形式 ,在近似“磁滞”碰撞力模型中引入了速度因子 ,得到碰撞力模型 ;将摩擦作用划分为滑动、滚动和转动三种类型 ,分别考虑其影响 ;综合考虑接触力和摩擦力 。
A vectorial frictional impact model is developed on the basis of several other models. In this model, some basic relationships are defined as generic functions fixed by experiments or theoretical estimations. The hysteresis-like impact model is modified by introducing the velocity factor. Then the impact force model is established. The effect of friction is divided into three parts: sliding, rolling and spinning, taken into consideration separately. Incorporating the impact force and the frictional force, a frictional impact model in three-dimensional space is eventually gained in the vectorial form and used for mobile weapon system.
