摘　　要：针对引信共线装定过程中分布电容影响装定可靠性的问题,建立基于装定器模块、能量与信息传输模块、引信电路模块的等效电路模型。分别研究在装定输出信号为高电平时和低电平时两种情况下,分布电容对共线装定系统信息传输特性的影响。得出高电平时分布电容对共线装定系统影响较小的结论,并推导低电平时引信识别到的接收信号的低电平脉宽与分布电容的关系式。提出两种优化方法,一种利用二极管屏蔽外部因素如并入电缆引入的电容;另一种利用并联一个阻值较小电阻的方法来降低系统的时间常数,从而提高引信识别到的低电平脉宽,提高装定可靠性。经仿真和实验验证,两种方法均提高了引信识别接收信号的可靠性。An equivalent circuit model based on the setter module,the energy and information transmission module and the fuze circuit module is established for the effect of distributed capacitance on the setting reliability in the process of fuze collinear setting.The influences of distributed capacitance on the information transmission characteristics of collinear setting systemwhen the setting output signal is at high level and low level are studied,respectively.The conclusion is drawn that the distributed capacitance has little influence on the collinear installation system at high level,and the relationship between the low-level pulse width of the received signal recognized by the fuze and the distributed capacitance at low level is deduced.Finally,two optimization methods are proposed,one uses a diode to shield the external factors,such as the capacitance introduced by the incorporated cable,and the other uses a parallel-connected resistor with a smaller resistance to reduce the time constant of the system,thereby improving the recognition rate of the fuze.The low-level pulse width improves the reliability of fuze setting.The simulation and experimental verification show that both methods improve the reliability of the fuze to identify the received signal.
