Shock absorber is a device used to absorb shocks in an automobile. The energy required to damp these vibrations is wasted in the form of heat. A regenerative shock absorber transfers this vibration into electrical energy while satisfactory performance could be maintained. Here the suspension system is considered to be undergoing free vibrations under road shock and the maximum displacement that it can undergo upon traversing over a pothole or road unevenness has been found. This displacement was found using a developed Matlab code and verified using ANSYS Workbench. A rack and pinion arrangement is provided to transmit the displacement of the spring and in turn coupled with a generator. The rack is attached to the suspension and the pinion is coupled with a DC motor. When the vehicle travels over a pothole there will be a vertical movement in the suspension. Since the rack is attached to the movement gets converted to the rotating motion of the pinion which rotates the DC motor and produces electric power. The energy produced so can be used for the running of auxiliary lights or charging the battery in an electric vehicle. Thus the efficiency and range of the vehicle can be enhanced.
