Abstract :
A novel approach to make magnetorheological (MR) dampers self-sensing based on the magnetic flux linkage measurement and the working principle of an integrated relative displacement sensor (IRDS) integrated into a commercially available MR damper are presented. The IRDS mainly comprises an exciting coil wound on the piston head and an induction coil wound on the nonmagnetic cylinder, which is covered by a cylindrical cover made from the materials with high magnetic permeability. In order to validate and optimize the performance of the IRDS, the modeling and analyzing with the finite element method based on ANSYS are carried out and the simulation results are presented.
