    摘要:

    针对常用破片速度及飞散特性测量方法存在的问题,开展了破片速度及飞散特性一体化测量方法的研究,设计了一种阵列式破片速度及飞散特性一体化测量系统。测量系统以断通式梳状靶为阵列单元组建测量靶,基于多路同步计时方法,得到破片飞行时间与着靶位置,结合相关测量原理,获得破片速度与飞散特性。开展了验证试验,结果表明:该系统能实现破片速度及飞散特性的一体化测量,在破片飞散特性测量上,与人工统计的结果相比,破片捕获率及分布密度测量精度都至少提高了3%,飞散角测量误差低于5%,验证了测量系统可行及测量结果可信,为破片速度及飞散特性的一体化测量提供了一种有效的测量手段。

    Abstract:

    Aiming at the problems existing in common measurement methods of fragment velocity and scatter peculiarity, the integrated measurement method of fragment velocity and scatter peculiarity is studied, and an array-type integrated measurement system is designed in this paper. The integrated measurement system takes the comb target as the array element to construct the measurement target. Based on the multi-channel synchronous timing method, the flight time and target location of fragment are obtained. Combined with the correlation measurement principle, the fragment velocity and scatter peculiarity are obtained. The validation test result shows that the system can realize the integrated measurement of fragment velocity and scatter peculiarity. In the measurement of fragment scatter peculiarity, compared with the results of manual statistics, the fragment capture rate and the measurement accuracy of distribution density is improved by at least 3%, and the measurement error of scatter Angle is less than 5%. It verifies the feasibility of the integrated measurement system and the reliability of the measurement results. The system provides an effective measurement method for the integrated measurement of fragment velocity and scatter peculiarity.
