在分析雨场及雨滴特性的基础上,用蒙特卡洛方法进行数字仿真,数字计算弹头引信在暴雨中受雨碰撞的频度。主要计算弹丸在雨区中的弹道长度,连续2次碰撞之间的平均距离,弹丸在两雨滴之间的飞行时间等。研究结果表明,引信头部在雨区中的碰雨频率很低,特别是直径较大的雨滴。雨区中雨滴对引信头部防雨装置的碰撞可做单个碰撞来分析。这为引信受雨滴冲击变形的计算以及引信防雨装置的参数设计打下一定的基础。
On the basis of analyzing the characteristics of rain field and raindrops, the Monte Carlo method was used to carry on the numerical simulation, and the frequency of the warhead was calculated numerically by the rainfall. Mainly calculate the trajectory length of the projectile in the rain area, the average distance between two successive collisions, the time of flight of the projectile between the two raindrops, and the like. The results show that the frequency of rain touching the head of the fuse in the rain area is very low, especially the rain droplets with larger diameter. Rain rains in the head of the fuse unit of the rain device collision can do a single collision to analyze. This fuze by the raindrop impact deformation of the calculation and fuze rain device parameters laid the foundation.
