There are many failures in the reed switch components used in the aircraft differential pressure system,which seriously affects the training tasks of the troops.Combined with the reed structure and the vibration and high and low temperature environment in actual use,the fault mechanism is analyzed,and the improvement scheme is put forwardThe influence of vibration and high and low temperature environment on the performance of the reed switch components is studied by simulation and experiment,and the performance of the reed switch components before and after optimization is compared and analyzed.The results show that the improved scheme is effective,and the per formance of the improved reed switch components is more stable,which can be reliably applied to the aircraft differ ential pressure system.This fault analysis improvement can provide theoretical support for the design of reed switch products.
