A Study of Linear Regenerative Electromagnetic Shock Absorber System

The objective of this research paper is to design and develop a linear regenerative electromagnetic shock absorber for automotive suspension system. The significance of the arrangement of magnetic and coil materials as components of the linear regenerative electromagnetic shock absorber is to generate continuous electric energy to deliver power to a vehicles electronics.

Different magnets and coil arrangements will be reviewed and analysed. Additionally, a novel design of linear regenerative electromagnetic shock absorbers will be modeled by using the computer aided design software program (SolidWorks®) and tested using apparatus such as a shock absorber dynamometer.

The linear regenerative electromagnetic shock absorber system was simulated by using Matlab® and Simulink®. The simulation model was established and validated via experiments. The validated simulation model was then used for the analysis of the system parameter sensitivity. The sensitivity analysis then lead to the design optimization phase which allowed for the harvesting of maximum vibration in the design phase.
