运动构件碰撞分离的辨识及其再次碰撞研究

CRITERION ON THE RECOGNITION OF SEPERATION OF TWO COLLIDING COMPONENTS AND THEIR RE-COLLISION

在已有的系统动力有限元方程基础上,通过引入碰撞分离和再次碰撞的辨识准则,进一步研究了运动构件间的碰撞问题。首次提出了分析运动构件多次碰撞问题的一种数值计算方法,为深入研究自动武器闭锁机构运动构件的强度与寿命问题,提供了一条分析途径。实例表明,本文结果有足够的精确性。

On the basis of the dynamic finite element equation, the problem of collision among moving components is surveyed, with the introduction of a criterion on the recognition of the seperation of two colliding objects and their re-collision. A method of computation for the analysis of moving components colliding repeatedly is then put forward. This provides a way of analysis for problems of strength and life of moving components in an automatic weapon. An example shows that the method leads to results of enough accuracy.
