Paper Title:
Numerical Simulation of a Self-Decoupling Magneto-Rheological Damper on Electromagnetic-Thermal Coupling
  Abstract

Based on electromagnetic-thermal coupling field mechanism, a large-scale finite element analysis model for electromagnetic-thermal coupling global damper is established by ANSYS software. Electromagnetic field and temperature field sequential coupling analysis method is used in this study. Relative permeability and resistivity of magnetic material with temperature is also considered in the FE model. The simulation results show that the temperature of self- decoupling magnetic damper rises rapidly under external excitation, the temperature changes the magnetic fluid yoke and the materials’ core parameters, magnetic flux density in damper channel gradually decreases with the time, and the damping force decreases, finally the high temperature decline phenomenon is revealed.
