The electromagnetic relays used in military engineering are required to have extremely high reliability. When fai?lure occurs,the cause of the failure must be found out to prevent the same situation from happening again. The failure analysis methods of the electromagnetic relays used in military engineering are summarized. The failure modes and failure mechanisms of electromagnetic relays which were failed in storage and working are analyzed. Typical factors which cause the failure of electro?magnetic relays,such as mechanical deformation,environmental stress and mechanism of action are analyzed in detail. On this basis,two actual failure cases of the military electromagnetic relays are studied. Finally,based on the analysis of failure modes and failure mechanisms,some proposals to improve the reliability of electromagnetic relays are proposed.
