摘要
改进了在动爆条件下基于弹药炸点的破片区截测速方法,分析了破片贯穿靶板后的速度偏转现象,提出了一种采用归一化方法结合最小距离原则进行破口点集配准,以此识别破片飞散方向的方法。模拟试验结果表明,63.3%的破片角度测量误差绝对值在4°以内,86.7%的破片测量误差绝对值在8°以内。该方法易于实施,数据处理简单,为实战条件下弹药威力场的测试及毁伤效应研究提供了技术手段。
The velocity deflection angle after the fragments penetrated the target was studied,and the method of normalization combined with the principle of minimum distance was proposed for point sets registration.According to the results of the simulation test,63.3%of the fragment angle measurement errors are within 4°,and 86.7%of the fragments are within 8°.This method is easy to carry out and simple in data processing,which provides a technical means for testing the power field of ammunition and studying the damage effect under actual combat conditions.
