DESIGN OF ELECTROMAGNETIC REGENERATIVE SHOCK ABSORBER AS A TOOL OF HARVESTING VIBRATION ENERGY ON VEHICLE

Abstract

This paper discusses vibration energy on the vehicles shock absorber which was converted to electrical energy by using magnet and coil. Principally, vibration energy on the shock absorber will be wasted into friction and heat form. But, in this study are able to obtain the vibration energy and utilize it as a new energy source for the vehicle by adding the mechanism of harvesting energy electromagnetic type. Linear movement of the shock absorber is captured by electromagnetic generator mechanisms which consist of a coil and a permanent magnet. The produced output of the electromagnetic generator can be used as new energy source for the vehicle. The mechanism of harvesting energy used electromagnetic generator was chosen through literature study that has been done by the researcher. Furthermore, the electromagnetic generator obtained the smallest of energy loss. The experimental measurement used galvanometer, the results were obtained that the resurrection energy was 2.5 mV on 1.5 Hz, 4.24 mV on 2.0 Hz, and 5.6 mV on 2.5 Hz on excitation frequency.
