Design selection and analysis of energy regenerative suspension

Abstract

Nowadays, world demand for alternative fuels has led to an advanced research and development of hybrid and electrical vehicles. This paper presents the design development and analysis of energy regenerative suspension (EReSS) system to harvest wasted energy from vibration of a vehicle. The source of the wasted energy is the kinetic energy produced by the vibrating structures of the vehicle. Electromagnetic method was used to harvest the wasted energy. Several design concepts of the EReSS are discussed and proposed in this paper. Three-dimenstional (3D) modeling of the EReSS was performed using the Computer-Aided-Drafting (CAD). Design analysis was performed in order to find the best conceptual design of the EReSS, which then it will be fabricated. From the design analysis, the EReSS is attached as retrofit, outside the suspension system, and it will not disrupt the current suspension system. By the help of a moving suspension system, it helps vehicles to move smoothly on irregular road surface conditions.
