摘要
为分析部队实弹打靶中某型引信早炸率过高的原因,解决该引信实战使用难题,提出了实验室内打靶引信互扰效应试验方法,开展了不同影响因素下两引信互扰效应试验,分析了引信互扰效应规律,确定了引信失效机理。研究结果表明:引信相对速度、相对姿态、相对高度、辐射能量、辐射频率都会对引信临界互扰距离产生影响;引信早炸原因是各种因素的影响使得相互靠近的两引信辐射频率和能量不断变化,当两引信辐射参数满足频率牵引要求时,导致引信检波电压波动,从而推动引信执行电路误动作。战场使用时,受设计技术原因,在进行受试引信连齐射时,早炸问题无法避免,但合理调整火炮布局可以有效降低引信的早炸率。
To analyze the cause of the excessive early-destruction rate of a certain fuze in target practice,and slove the use problem of the fuze,an experimental method in the laboratory is advanced. The interactional effect experiments of two fuzes are done in different conditions. Interactional effect rules of fuzes are analyzed,and the failure mechanism is explained. The research results show that relative pose,relative height,relative velocity,radiation energy and radiation frequency can affect the threshold interactional distance. And the early-destruction reason is that the radiation parameters are changing when the fuzes move to each other,and the frequency pulling happens when the radiation parameters meet the requirements. The detection voltage fluctuates to lead to the mis-action of the fuze. Owing to the design technology,early-destruction can not be avoided in fusillade. But the self-destruction rate can be reduced effectively when the artilleries are positioned in a reasonable distance.
