Abstract:
Regarding the problem that the external power supply is required in the current magneto-rheological(MR) damper system,a self-powered MR damper is designed based on the piezoelectricvibration energy harvesting technology. The structure and dynamic equation for the self-powered MRdamper are derived. A prototype is fabricated and tested to evaluate the vibration isolation capabilityof the self-powered MR damper. The test results show that, under the outside vibration, the self-powered MR damper can collect the electric energy to activate electromagnetic coils inside thedamper,change its damping characteristics,and achieve the self-powered function.
