摘　　要：针对部队实弹打靶中某型引信早炸率过高的问题,提出了引信互扰效应试验方法,开展了引信互扰效应试验,分析了该型引信的互扰效应规律,并确定了其失效机理.试验结果表明:引信相对速度、相对姿态、相对高度、辐射能量、辐射频率以及加电方式都会对引信临界互扰距离产生影响.引信互扰效应机理为:引信靠近过程中,由于辐射能量及辐射频率接近而产生频率牵引,导致检波电压信号波动,从而推动引信执行电路误动作.To solve the problem of high early-destruction rate of a certain fuze in target practice,an experiment method is proposed.Interactional effect experiments were done.And the interactional effects rules were analyzed.Also,the failure mechanism was got.The experiment results show that many factors affect the threshold interactional distance,such as relative velocity,relative pose,relative height,irradiation energy,irradiation frequency and power supply manner.The failure mechanism is that when the fuzes move to each other,frequency pulling occurs because the irradiation energy and frequency are close,and the detection voltage signal is fluctuate,which leads to the mis-action of the fuze.
