Problems solved by technology

[0003] However, since the electro-hydraulic composite cylinder completes the force transmission by the mutual engagement of the screw and the nut, its ability to bear impact is poor, which limits the application of the electro-hydraulic cylinder in the frequent impact environment

Abstract

The invention relates to the technical field of hydraulic transmission and electromechanical transmission, in particular to an active control vibration reduction system and method based on an electro-hydraulic composite cylinder, the system comprises a reversing valve matched with the electro-hydraulic composite cylinder and an electromagnetic proportional switch valve connected with a rod cavity and a rodless cavity, and by judging the load and the vibration acceleration direction, the active control vibration reduction effect is achieved. The opening degree of the electromagnetic proportional switch valve and rotation of the motor of the electro-hydraulic composite cylinder are controlled, the purpose of relieving impact loads is achieved, the reliability of the electro-hydraulic composite cylinder is greatly improved, and the service life of the electro-hydraulic composite cylinder is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission and electromechanical transmission, in particular to an active control vibration reduction system and method based on an electro-hydraulic compound cylinder. Background technique [0002] Electro-hydraulic composite cylinder is a kind of electro-mechanical linear actuator: on the basis of converting the rotary motion of the motor into the linear motion of the screw drive pair through synchronous belts, reducers and other devices, and adding high pressure similar to the hydraulic cylinder. A new type of transmission in which oil drives the movement of the piston. Compared with the hydraulic transmission system, the advantages of the electro-hydraulic composite cylinder are high control precision, fast response and high transmission efficiency. The principle of the hydraulic transmission system is that the high-pressure oil output from the power source is distributed by the control v...
