摘要:
针对某型导弹发动机用电点火器在发火测试时出现的负压情况，进行了故障树分析排查、等效电路分析和试验验证，最终找到了该故障的原因是产品发火后绝缘性能失效，造成发火电路与测试电路耦合,形成电流回路，进而使电荷放大器输出端形成负压。对历次火工品发火测试时出现负压的情况进一步理论分析和试验验证表明，仅在使用压电式传感器的测试过程中出现负压，而应变式传感器则不会出现该故障。对分析电点火器类产品输出p-t曲线异常提供了参考。
Abstract:
Fault tree analysis, equivalent circuit analysis, and experimental verification were conducted to investigate the negative pressure situation that occurred during the ignition test of an electric igniter for a certain type of missile engine. Finally, the cause of the fault was found to be the insulation performance failure of the product after ignition, resulting in the coupling of the ignition circuit and the testing circuit to form a current loop, which in turn caused negative pressure at the output terminal of the charge amplifier. Further theoretical analysis and experimental verification were conducted on the occurrence of negative pressure during the ignition tests of various pyrotechnic devices. The results indicate that negative pressure only occurs during the testing process using piezoelectric sensors, while it does not occur when using strain gauges. It could provide a reference for analyzing the abnormal output p-t?curve of electric igniter products.
