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...

AI Technical Summary

Problems solved by technology

[0006] The current active energy-feeding suspensions are mainly electromagnetic and hydraulic-electric, among which the electromagnetic energy-feeding suspension with more researches has a lower carrying capacity and is mainly used for passenger vehicles with small weight and good road conditions. vehicles, the energy recovery potential is limited; in addition, the static load problem in the electromagnetic energy-regenerative suspension has not been well solved

However, its hydraulic circuit is complicated, which reduces the reliability of the system and limits the energy feeding efficiency
