Abstract
Dumpers are crucial in vehicle suspension systems as they absorb kinetic energy from the car's movement and dissipate it as heat. However, this energy is typically lost and, therefore, not utilized for propulsion, limiting overall energy efficiency. In recent works, researchers have studied regenerative hydraulic dumpers, which can convert part of the dissipated energy into electrical energy for powering the vehicle or storing in batteries. The present study proposes to evaluate power harvest potential in a quarter-car model. Employing road profiles based on ISO 8608:2016 with specific roughness and frequency characteristics, simulation results demonstrated the regenerative hydraulic dumper's ability to convert a significant amount of dissipated energy into usable electricity with rougher surfaces and lower frequencies. This research provides valuable insights into their behavior under different operating conditions, qualifying further development for significantly reducing transportation's environmental impact while improving overall energy performance.
