Abstract:

The bistable crystal cover relay has outstanding adaptability to the endurance environment,but there are the quality problems such as small debugging margin and large product dispersion,which is difficult to meet the requirements of continuously improving reliability indicators of electronic systems.Aiming at the problems such as poor anti-interference of output characteristics caused by the imperfect reliability design theory of relays at present,the simulation model of relay electromagnetic system and contact spring system is established.The robust design method proposed by Taguchi Genichi is used to optimize the relay product parameters and their tolerances in order to improve their reliability.The research conclusions are applied to the improvement of a certain type of electromagnetic relay,and its related methods can be applied to the design of other electrical products,which can provide the necessary research methods and foundations for the robust design of electromagnetic relays.
