基于能量域的引信环境识别

Fuze Environment Recognition Method Based on Energy Domain

针对目前引信对高性能安全控制及对弱环境精细化识别的要求,提出一种基于能量域的环境识别方法。通过对安全系统中存在的能量转换过程进行分析,该方法基于梯形法近似积分计算,通过输入模拟弱发射环境进行了仿真分析。数值仿真结果表明,该方法在弱发射过载环境中效果良好,且能够降低在发射过载变化时的解保距离散布,能够识别故障发射环境,勤务处理安全性和可靠性均有所提高,可为引信安全系统设计和解保策略的制定提供参考。

Aiming at the current requirements of fuze for high-performance safety control and refined identification of weak environment,an environment identification method based on energy domain was proposed.Through the analysis of the energy conversion process in the safety system,an environment identification method based on the approximate integral calculation of the trapezoidal method was proposed,and the simulation analysis was carried out by inputting the simulated weak launch overload environment.The numerical simulation results showed that the identification method had a good effect in the weak launch overload environment,and could reduce the dispersion of the arming distance and recognize the faulty launch environment with the launch overload changing.The service processing security and reliability were improved.It could provide a reference for the design of fuze safety system and the formulation of arming strategy.
