Energy Harvesting Shock Absorbers for Vehicles: Design, Modeling and Simulation

Abstract:

Energy harvesting shock absorber is used for harvesting the kinetic energy in the vehicle suspension vibration. In this paper, we present design, modeling, and simulation of a novel energy harvesting shock absorber based on rack and pinion mechanism. The shock absorber consists of three main components: the mechanical vibration input, the transmission module, and the micro-generator module. The shock absorber is installed between the vehicle frame and chassis to obtain a relative linear motion acting as mechanical vibration input. The function of transmission mechanism module is to convert the relative linear motion to a unidirectional rotation for the input shaft of micro-generator. The micro-generator will produce electricity due to the input shaft rotating in one direction. This shock absorber was tested in simulation condition, and the last performance evaluation demonstrates the validity of the proposed energy harvesting shock absorber.
