In order to determine the damping characteristics of the electromagnetic shock absorber under different working conditions

the theoretical modeling and test of the electromagnetic shock absorber with mechanical rectification device were carried out. Firstly

the dynamie transmission model and electromechanical coupling model of electromagnetic shock absorber were built theoretically

and its dynamics and electrics characteristics are analyzed. Secondly

a test bench of electromagnetic shock absorber is built from the engineering point of view

and the experimental study of its damping characteristies under different working conditions was carried out. Finally

the theoretical simulation results were compared with the test results. The results show that theoretical results and test results have the same variation trend. The equivalent damping coefficient of electromagnetic shock absorber will decrease from 1 208 N・s/m to 496 N・s/m when the load resistance increases from 5 Ω to 100 Ω. In addition

the results of decrease of equivalent damping coefficient from 874 N・s/m to 660 N・s/m when the increase of excitation frequency from 0.5 Hz to 2 Hz or the increase of excitation amplitude from 20 mm to 40 mm.
