The Experimental and Theoretical Research of the New Electromagnetic Damper Reduction on Earthquake Resistance and Disaster Reduction
It is an innovative work to make the electromagnetic damper with strong magnetic material. Firstly, the structural research and the experimental research on the basic performance of electromagnetic damper have been made. Then the theoretical research is conducted based on the above research results. Thus, the paper put forward and deduced the electromagnetic damper restoring force model and the motion parameter’s effects on its performance. Such as vibration frequency and amplitude are also studied in the paper. The results showed that the new electromagnetic damper is characteristic of simple structure and good performance and that the theoretical model coincides well with the results obtained from the experiments. Keywords：strong magnetic material, electromagnetic damper restoring force model, vibration frequency, motion amplitude value.
