Abstract:
In order to study the magnetic field distribution of a multi-coil magnetorheological damper, the magnetic circuit of the multi-coil magnetorheological damper is theoretically analyzed, and the computational method for the magnetic induction intensity in the effective damping gaps of the multi-coil magnetorheological damper is proposed based on the magnetic circuit Ohm’s law. The finite element model for the multi-coil magnetorheological damper is established by using the general finite element software, and the magnetic induction intensities of the effective damping gaps in different magnetic fields are calculated. The computational model for the magnetic field distribution of the multi-coil magnetorheological damper is established by using the Gaussian function and the exponential function to simulate the magnetic field distribution law and the influence of the current on the magnetic field, and the corresponding computational formulas are also given. The results show that the magnetic induction intensities of the damping gaps can be calculated effectively and quickly by using the proposed model in different magnetic fields, and the calculation results by the proposed model agree well with the simulation results by the finite element model. The proposed model lays a foundation for the damping force calculation and the optimal analysis of current inputting.
