Abstract: An energy-regenerative air suspension was designed, which used the new absorber to regenerate vibration energy and then store into effective energy of high-pressure air. Its structure and working principle was introduced, and its simulation model combining with AMESim-Simulink was established to analyze its damping characteristics and the energy utilizing capacity of the energy-regenerative air suspension on the vehicle vibration. The results show that the new absorber has good external characteristics; the energy-regenerative air suspension could regenerate vibration energy with high efficiency and inflate the high-pressure gas tank to the requested pressure in a short time. So the proposed suspension could save electric energy which is used to drive electric air compressor for vehicle, which has good economic benefit and practical significance.
