摘　　要：通过“-40℃,4 h”低温存储试验研究了低温环境对A(钽电容)、B(电解电容)、C1(电解电容)及C2(钽电容)4种带点火药头电子控制模块的发火性能的影响,使用示波器测试了4种样品的发火电容在发火流程各阶段的电压值变化。研究发现:经过“-40℃,4 h”存储,试验前后钽电容及电解电容在发火流程各阶段的电压值没有明显变化,A(钽电容)和C2(钽电容)样品的发火电容性能没有影响;在-40℃环境下,B(电解电容)和C1(电解电容)中0 h-1#、0 h-2#样品均未发火,电解电容无法正常工作。The influence of low temperature environment on the ignition performance of four types of electronic control modules with ignition heads A(tantalum capacitor),B(electrolytic capacitor),C1(electrolytic capacitor)and C2(tantalum capacitor)is studied through the“-40℃,4 h”low temperature storage experiment.The voltage changes of the ignition capacitors of four samples in each stage of the ignition process are tested by oscilloscope.The study finds that:after the storage of“-40℃,4 h”,the voltage values of tantalum capacitor and electrolytic capacitor in each stage of the ignition process do not change obviously before and after the experiment,the ignition capacitor performance of samples A(tantalum capacitor)and C2(tantalum capacitor)are not affected,however,samples 0 h-1#and 0 h-2#with B(electrolytic capacitor)and C1(electrolytic capacitor)are not ignited at-40℃,and the electrolytic capacitor can not work properly.
