摘要：

A novel magnetorheological damper (MRD) integrated with controllable damping, displacement self-induced and vibration energy harvesting ability was proposed to solve the problems of simple function integration and low efficiency of vibration energy harvesting in conventional MRD systems. The working principle of the proposed MRD was analyzed, especially the principle of vibration energy harvesting device with a single induction coil and a double induction coil, and winding frame with a non-magnetic and a low-magnetic material were explained in detail. Then, the vibration energy harvesting device with the single induction coil and double induction coil was simulated by ANSYS software. The prototype of the proposed MRD was manufactured, and the experimental test system was also set up. Afterwards, the energy harvesting performance of the developed MRD with the single induction coil and double induction coil was experimentally tested, respectively. The experimental results showed that the induced voltage with the double induction coil was 2.512 V and the energy harvest power with the double induction coil was 1.5 W under the sinusoidal displacement excitation with 7.5 mm amplitude and 4 Hz frequency, and the energy harvesting efficiency was about twice of that with the single induction coil. In addition, the energy harvesting efficiency with the non-magnetic and low-magnetic winding frame of the proposed MRD was almost the same. © 2020, Chinese Society of Agricultural Machinery.
