Struct. 22 025008 DOI 10.1088/0964-1726/22/2/025008 Energy-harvesting shock absorbers are able to recover the energy otherwise dissipated in the suspension vibration while simultaneously suppressing the vibration induced by road roughness. They can work as a controllable damper as well as an energy generator.
The conventional hydraulic shock absorber is responsible for absorbing vibration energy caused by uneven road excitations and maintaining the vehicle’s comfort and handling. Simultaneously, the vibration energy is wasted in the form of heat to the environment. RSA may transform vibration energy into electrical energy for later use.
Several studies reported that conventional shock absorbers are liable for 30% of energy dissipated at wheel systems, which is approximately 10% of the total vehicle fuel consumption (Abdelkareem et al. 2019). The RSA can recover waste vibration energy from the suspension system while reducing the vibrations (Cai and Zhu 2022).
The ER shock absorber had a rack-pinion mechanism that converts linear motion into rotary motion, and the generator was coupled with it to harvest vibrational energy. The harvested energy was utilized to energize the ER fluid to produce the required damping for the vehicles.
Conclusion An energy regenerative shock absorber is able to harvest the kinetic energy from the vehicle suspension vibration. This paper presented the design, modelling, simulation and test of a novel energy regenerative shock absorber based on dual-overrunning clutches for electrical vehicles.
Advanced studies show that 3% to 12% of total energy is dissipated in shock absorbers in the form of vibration and heat . Energy can be harvested from the environment, including mechanical motion , body movement , thermal , solar and wind .
