摘　　要：研究无线电引信中军用电容的高过载特性具有重要的意义,通过动态测试军用电容高过载下的特性,可以为系统地研究引信高过载特性提供可靠的依据。针对无线电引信中军用电容的工作环境,设计了军用电容在高过载条件下的动态测试试验方案并进行实验。最后,通过实验对高过载下军用电容的参数变化规律和失效模式进行了探讨,分析了电容参数变化及失效对引信的影响。The high overload characteristics of military capacitors in the radio fuze is an issue of great significance.The dynamic testing of the military capacitor characteristics under high overload provides a reliable basis for systematic research on the high overload characteristics of fuzes.In this paper,a dynamic testing for a military capacitor under high overload condition is designed and experimented based on the working environment of the military capacitor in the radiao fuze.Based on the experiment,the parametric variation and failure mode of the military capacitors under high overload are discussed,and the influence of the capacitor parametric variation and failure on the fuze is analyzed.
