Design and operational analyses of an electromagnetic hybrid shock absorber system for scooter application

Abstract

To effectively harvest the inherent vibration energies, feasibility of replacing those common mechanical shock absorbers that are mounted between the wheels and bogie of a scooter with electromagnetic motion device will be assessed. Instead of consuming additional energies to control the vibration patterns, the main design objectives are to produce the suspension forces to meet the maximum encountered force specifications, and to convert the input mechanical vibrations to electric energies directly. Based on proper emulation designs and electric output controls, the operational fluxes and dynamic characteristics of this hybrid suspension system at various operational conditions will be thoroughly investigated, and the satisfactory performances of the proposed system can then be systematically validated.
