Design and Analysis of Electromagnetic Shock Absorbers

This project aims to explore energy recovery from vehicle suspensions by addressing two key questions: how can wasted energy be converted into electricity, and how efficiently can this conversion occur? To achieve this goal, a retrofit rack-pinion-based electromagnetic regenerative shock absorber is designed and modeled using CATIA V5 software. The shock absorber's components are analyzed considering factors such as tire weight, bike weight, and the weight of two persons. The proposed design operates on a rack-and-pinion mechanism to generate power by converting linear movement into rotary motion via bevel gears. Regenerative shock absorbers offer potential for not only harvesting kinetic energy from suspension vibration but also serving as actuators for suspension control. This technology can boost fuel efficiency by reducing the demand on car alternators, decreasing engine workload. The report provides an in-depth explanation of the design, modeling, and analysis of its parts, with structural analysis conducted using ANSYS WORKBENCH 14 validating the strength of the design.
