It is of great significance to study characteristics of PMA for improving the reliability of electric railway. The simulation model of single-stable PMA was established based on Ansoft Maxwell12.1 software. The characteristics of the open and closing coil were analyzed and calculated by the finite element method. Through the adjustment of each parameter, steady magnetic distribution and a few simulation curves such as position, current and movable contact velocity were obtained, and experiments were also carried out. Then the accuracy and reliability of simulation were proved.
