Abstract: In the current magnetorheological (MR) damping system, separate power supply is required. This paper addresses the feasibility and effectiveness of a new self-powered MR damper which contains an electromagnetic inductive (EMI) device and can harvest energy from the vibration in which it is deployed. The dynamic equation for the new self-powered MR damper is derived. A simulation study is conducted to check the ability of harvesting energy from the vibration. Based on the simulation, an electric energy conditioning module is designed to convert the harvested energy to stable voltage suitable to the MR damper. To evaluate the vibration isolation capability of the self-powered MR damper, a prototype of self-powered MR damper was designed, fabricated, and tested. The experimental results show that the self-powered MR damper is able to collect electric energy to activate electromagnetic coils inside damper and change its damping characteristics under vibration.
