Simulation on mechanism dynamic characteristics of single coil and single stable position contactor with permanent magnet

A simulation for mechanism dynamic characteristics of single coil and single stable position contactor with permanent magnet is carried out by using ANSYS and ADAMS software package. This simulation includes the following steps: with the use of ANSYS software package, the attraction characteristic of contactor with permanent magnet is simulated, which is based on FEA model; by constructing the mechanical model of contacts system and permanent magnet actuator, the dynamic and kinematic characteristics of contactor with permanent magnet are simulated with the help of ADAMS software package; the testing equipment is designed and the attraction characteristics and the kinematic characteristics are discussed. This paper shows this simulation can reduce the development period and design costs, supply technique support for the incessant, increase service lifetime and improve economic performance of contactor with permanent magnet.
