Abstract

The magneto-rheological damper (MRD) has been widely used to suppress shock and vibration, which has strong nonlinearities and electromagnetic interference (EMI) due to the displacement vibration, semi-active control strategy, excitation current and excitation coil. The transmission impedance of excitation coil should be determined and measured to calculate excitation current and design EMI filter, which can improve the MRD control effectiveness and mitigate EMI noises. However, the transmission impedance of excitation coil is active complex impedance, which can’t be determined by traditional passive impedance extraction method. To solve the problem, the transmission impedance model and equivalent circuit of MRD is proposed and analyzed. Moreover, a novel transmission impedance extraction method is designed to obtain the transmission impedance of excitation coil online. The theoretical and experiment results show that the transmission impedance of three ferrite core with different turns can be determined. The transmission impedance of Lord MRD RD-8040-1 can be obtained by employing the present method, which comply with theoretical results well. The transmission impedance of MRD at characteristic frequency is growing with excitation current increasing, which verify the MRD transmission impedance model and extraction method efficient and effective.
