Many researchers have designed various regenerative shock absorbers (RSA) to transform vibration energy into electrical energy that can charge electric vehicles' batteries and power low-wattage devices. The present work focuses on an in-depth summary of rotary, hydraulic, and linear electromagnetic. This article analyzes the energy recovery potential of two types of rotational EHSA, those that use ball-screw and those based on cable transmission. The innovative device provides for superposition of radial components of the. At present, the existing shock absorption technology uses the shock absorber to complete the absorption and shock absorption of the impact force, and uses the damper to accelerate the attenuation of the vibration energy.
