摘　　要：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 rainfields and raindrops,this paper calculates the impacting frequency with Monte Carlo method when PD fuze impacted by raindrops in rainstorm.The calculation includes the ballistic lengths in rainfield,the fuze′s average distances between two continuous collision and the fuze′s average interval between two continuous impacting.The results have shown that the impacting frequency is very small when PD fuze traverses in a rainstorm,especially to large raindrops.Then such collisions between some large raindrops and rain insensitive devices can be analyzed as a discrete impacting.These works will be useful for the further calculation of the impacting distortion when PD fuze impacted by raindrop and the parameter design of rain insensitive device of PD Fuze.
