“…A vehicle's damping system control should comply with specific purposes, such as passenger riding comfort and the vehicle's handling quality improvement [14][15][16][17]. A recent study demonstrated a significant enhancement in harvested power and the frequency bandwidth of a multimodal electromagnetic vibration energy harvester, consisting of arrays of coupled levitated magnets [18], when the device is excited beyond its critical Duffing amplitude [19].…”

Shock absorbers allow the damping of suspension vibrations, by dissipating kinetic energy. This energy theoretically can be harvested; however, practical solutions are not easily obtainable. This paper is dedicated to analyzing and evaluating the vibration energy in a vehicle's suspension that is generated by road excitations. Also, it estimates the possible amount of harvested energy required to diminish accelerations of the vehicle body, the driver, or the passenger center of mass. The control of damper is realized by optimizing the best damping coefficient for different road roughness. Analytical results, obtained from the proposed dynamic model of the car, were compared with experimental data, showing a good coherence between them. These results allow us to evaluate the amount of energy circulating within shock absorbers and give information about the amount of the possible harvested energy. There is a very good relationship between energy needed for control and gained energy.
