摘要
侵彻弹体过载信号是反映侵彻物理过程的关键信号,可分为刚体减速度、弹体结构响应、连接结构响应和传感器噪声4种成分。介绍了4种成分的来源和各自特点,讨论了弹体结构响应和传感器相关信号各自的建模和评估方法。整理了针对过载信号进行分析处理的若干方法,比较了各种方法的精确性、自适应性、实时性和适用范围。对于过载信号处理实时性需求、重构手段、刚体减速度在复杂侵彻环境下的形式以及高速侵彻对过载信号分析处理带来的挑战展开了讨论。针对侵彻弹体过载信号研究现状,总结了存在的问题以及未来可能的研究方向。
The overload signal of penetrating projectile is of vital importance to reflect the physical process of penetration,which further helps to reveal the mechanism of penetration resistance and the structural response of projectile.It is also an important basis for designing the projectile-fuze system and achieving the precise target strikes.The overload signal is divided into four components:rigid body deceleration,structural response of projectile,response of connection structure and interference signals of sensors.The sources and characteristics of the four components are introduced,and the modeling and evaluation methods for the vibration and sensor-related signals of projectile-fuze system are discussed.For analyzing the components of overload signals,the low pass filtering,mechanical filtering,modal decomposition,wavelet transform,and blind source separation methods are discussed respectively.The accuracies,adaptabilities,real-time performances,and applicabilities of the methods above are also compared.The real-time requirements for overload signal processing,the signal reconstruction methods,the form of rigid body deceleration in complex penetration environments and the challenges brought by high-speed penetration scenario are discussed.Based on the current research status of overload signals processing of penetrating projectiles,the existing problems and possible future research directions are summarized.
