Electromagnetic system (EMS) is the important part of automobile electromagnetic relay (EMR). A new approach integrating advantages of magnetic equivalent circuit (MEC) method and finite element method (FEM) was proposed to quickly calculate the dynamic characteristics of EMS. The approach is applied in dynamic modeling, design refinement and performance optimization, where repetitive calculation of electromagnetic character is needed. Taking increasing the contacts’ breaking velocity and decreasing closing velocity as goals, the EMS was optimized by particle swarm optimization (PSO), and the results indicate the feasibility of the approach.
