Abstract
Dynamic characteristic is key to optimize the design of permanent magnetic actuator. Based on the permanent magnetic actuator with multi-bar linkage, a new analytical method that calculates dynamic characteristic is proposed. Electromagnetic field is calculated by finite element method. With the secondary development of ADAMS software, the dynamic characteristics simulation could be performed through coupling the equations of mechanical system motion with the equations of electric circuit, electromagnetic field. It demonstrates that increasing the preload of breaking spring will result in shifting the dynamic characteristics of moving contact and armature forward, and have no influence on the total breaking time, and increasing the diameter of the armature will reduce the total breaking time and the exciting current. Experiments also have been done to verify the validity of the simulation results.
