Design of a Regenerative Inerter for a Semi-Active Vehicle Suspension System

The purpose of this analysis is to explore an advanced approach for efficiently transforming vehicle vibrations into energy with the intention of adapting damping based on road conditions. To delve into the dynamic control method for damping and energy retrieval from a regenerative damper, proposed utilization of an electromagnetic energy-gathering damper equipped with nine autonomously controlled coils. The utilization of a car’s dampers or shock absorbers is aimed at diminishing the vibration resulting from uneven road surfaces generated by the strains linked to vehicle maneuvers like acceleration and braking. The primary goal is to enhance ride comfort, vehicle handling, and maneuverability by minimizing vibrations through the dampers. While stiffer dampers provide improved stability and superior road control, softer dampers ensure a more pleasant driving experience. Both active and semi-active dampers can modify their damping attributes to strike a balance between ride smoothness and road preservation. Nonetheless, dynamic dampers necessitate significant power consumption, and semi-active dampers rely on external power supplies. Conversely, the regenerative inerter expounded in this research can be adjusted without relying on an external power origin.
