Abstract: In this paper, harvesting vibration energy from suspension is investigated. Theoretical values for the harvested energy are calculated. Experimental evaluation of the energy is performed using vehicle road simulation facilities. An excitation signal in the frequency range of 0.5 Hz to 20 Hz is applied to the vehicle and the harvested power is calculated. Experimental results give a maximum harvested power of 984.4 W at the highest frequency, which is close to the theoretically computed value of 1,106 W, for each suspension. Application of regenerative force actuators (RFA) is explored for harvesting the vibration energy and controlling vibration. It is shown that the harvested power increases with the value of the actuator constant.

Keywords: energy harvesting; vibration energy; regenerative force actuators; RFA; active control; vehicle suspension; simulation; vibration control; vehicle vibration.
