The cooperative characteristic of electromagnetic relay’s attractive torque and reaction torque is the key technique to ensure its reliability, and it is important to attain a better cooperative characteristic by analyzing and optimizing relay’s electromagnetic system and mechanical system. From the perspective of changing reaction torque of mechanical system, this paper takes adjusted parameters (armature’s maximum angular displacement αarm_max, initial return spring’s force Finiti_return_spring , normally closed (NC) contacts’ force FNC_contacts, contacts’ gap δgap and normally open (NO) contacts’ over travel δNO_contacts) as design variables, and gives the objective function with the purpose of increasing the breaking velocities of both NC contacts and NO contacts. And finally, genetic algorithm (GA) is used to accomplish the optimization of the objective function. |
