<![CDATA[This study investigates the potential of utilizing vehicle vibrations as an energy source through a regenerative shock absorber (RSA) system based on a rack-pinion mechanism and electromagnetic generator. The research comprises two main stages: experimental testing of the RSA and its implementation into a numerical half-car suspension model. Experimental data were used to establish the relationship between translational velocity, damping force, voltage, and current. The average damping coefficient obtained was 827.33 Ns/m and was applied in simulations. The results indicate that the highest voltage and current outputs occur at a speed of 90 km/h, which corresponds to the largest suspension deflection amplitude. Simulation outcomes also demonstrate that the RSA effectively functions as both a vibration damper and an energy harvester. This study confirms the dual-functionality of RSA systems in improving ride comfort while simultaneously converting mechanical energy into electrical energy.]]>
