Abstract

An analysis model for electromagnetic damper is proposed in order to obtain the working characteristics of electromagnetic damper under different working conditions. Firstly, the inertia force and the electromagnetic force of electromagnetic damper are calculated, and the friction force is tested. Secondly, by combining the theoretical results and the test data, the working characteristic analysis model for electromagnetic damper is established. Finally, the damping characteristics and energy harvesting characteristics of the electromagnetic damper under multiple working conditions are discussed by using the present model. The working condition characteristic surface of the electromagnetic damper is obtained by using the recovered energy and equivalent damping coefficient as the coordinate plane. The results show that the error between the calculated results and the test results is below 10%. The damping force and output voltage of the electromagnetic damper are positively correlated with excitation frequency and amplitude. The excitation amplitude and frequency influence the energy harvesting characteristic and damping property deeply, respectively. The increase in load resistance reduces the energy regenerative capacity and damping capacity of the electromagnetic damper.
