Abstract :
This paper concerns energy harvesting from vehicle suspension systems. Theoretical and experimental presentation of energy harvesting from suspension is explored. The generated power associated with random excitation inputs to vehicle is determined. The potential values of power generation from various road conditions are calculated. The effect of suspension energy regeneration on the ride comfort and road handling is presented. This includes study of tire deflection, damping, and spring stiffness for a regenerative suspension. The concept of self-powered actuation using the harvested energy from suspension is discussed with regards to applications of self-powered vibration control.
