摘要
Abstract
Fault tree analysis,equivalent circuit analysis,and experimental verification were conducted to investi-gate the negative pressure situation that occurred during the ignition test of an electric igniter for a certain type of missile en-gine.Finally,the cause of the fault was found to be the insulation performance failure of the product after ignition,resul-ting in the coupling of the ignition circuit and the testing circuit to form a current loop,which in turn caused negative pres-sure 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.关键词
