Energy crisis and environmental problems such as oil shortage and atmospheric pollution have brought challenges for new development of an energy saving, efficient and environment friendly power transmission system in vehicles. This research is focused on how to use the vibrational energy of the suspension system to generate power that would otherwise go as waste. It is demonstrated that the potential energy of driving vibration is sufficient to be utilized as a sustainable energy. The vibrations experienced by the shock absorber of the vehicle when passed through some irregularities on the road are converted into useful energy by using a regenerative linear or rotary mechanism. As shock absorber effect formed, spring is compressed, and linear movement of rack is converted in rotary motion due to pinion moves as the rack is meshed with pinion. And the pinion is mounted on the shaft of the generator which then produce the power. It is then used to calculate the practical power generated from the regenerative shock absorber by taking the real vibrations amplitude data from the road. The vibrations amplitude data is acquired from the road by driving motorcycle on different road conditions with the setup installed in it to calculate and store the vibrations amplitude data. Later, the same data is applied to the testing rig by using pneumatic and Arduino to find out the voltage generated. The power that is practically generated by testing the mechanism on the rig is around 9.5 watts. The harvestable power from the suspension depends on the vehicle speed, road roughness and stiffness of the tire. This regenerated energy is used to charge the battery.
