Description

Technical field [0001] The invention belongs to the technical field of vibration reduction, and specifically relates to a pump-type energy-fed active vibration reduction system capable of recovering vibration energy and performing active damping control. Background technique [0002] Vibration damping systems are widely used in places such as vehicle suspension systems, railway tracks, mechanical equipment and bridge construction. The main existing damping measures include friction dampers, mild steel dampers, rubber dampers, viscoelastic dampers, etc., most of which are Convert vibration energy into heat energy and dissipate it. [0003] Take vehicle shock absorbers as an example. At present, passive hydraulic shock absorbers are still widely used in automobiles. Their damping coefficient is not adjustable and cannot be changed with the external road conditions. The design can only ensure that the It can achieve good damping performance under different conditions, and it is diffi...
