Abstract

The storage degradation test system for aerospace electromagnetic relay (EMR) is designed, which uses FPGA and ARM SCM architecture as system's hardware core. The degradation data rule of pick-up time parameters for aerospace EMR is tested. And the variation law of pick-up time changing with time is obtained. The change of pick-up time is analyzed and verified, which is mainly caused by reeds reaction occurred relaxation. Then, pick-up time and reed reaction exists the approximate linear relationship was found. So, the pick-up time can characterize the degradation of reed relaxation. The storage degradation model of pick-up time is estimated through regression theory. The research results in this paper provide the necessary theoretical method and basis for studying storage reliability and life prediction of the aerospace EMR.
