FEM Investigation of Load Carrying Capacity of Magnetic Vibration Isolating Supports

摘要

The load carrying capacity of self-centering permanent magnet based vibration isolating support is analyzed in the article. COMSOL Multiphysics? modeling software was used for numerical simulation. Results are presented as repulsion force versus support cap displacement graph as well as magnetic flux density distribution graphs. Repulsion force was also measured experimentally. It is established that differences between numerically and experimentally obtained values are only about 2-8%. It is also established that near-zero stiffness of the support is achieved in case of 70 N normal load force.
