A Method of Impact Simulation in Permanent Magnetic Field

Abstract:

To simulate the impact response of the moving body in the permanent magnetic actuator, this paper takes the magnetic force of the moving body at different positions as one of the input loads for the impact simulation, which avoids the coupling calculation of the magnetic and impact problem. The static and transient analysis of the magnetic field in the permanent magnetic actuator are implemented respectively to compute the magnetic flux density and their relative errors, results show the moving body in this magnetic field exerts little influence on the magnetic intensity and the influence can be neglected. The force of the moving body with respect to its position can be calculated in the static analysis and then be imported into the impact calculation to obtain the velocity and displacement. By comparing these results with the ones from the magneto-mechanical coupling transient analysis, the difference is small which proves the feasibility and accuracy of the proposed method.
