Title:
DUALEXTRUDING, PIEZOELECTRICITY AND MAGNETORHEOLOGICAL COMPOSITE AND INTELLIGENT DAMPER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/073220
Kind Code:
A1
Abstract:
Disclosed is a dualextruding, piezoelectricity and magnetorheological composite and intelligent damper, comprising a working cylinder (6), wherein two ends thereof are correspondingly provided with a left end cover (5) and a right end cover (10); a piston (12) is arranged inside the working cylinder (6); two ends of the piston (12) are correspondingly fixedly connected to a first piston rod (1) and a second piston rod (11); the piston (12) divides the working cylinder (6) into a first cavity and a second cavity respectively arranged at two end sides of the piston (12), with the first cavity and the second cavity being filled with a magnetorheological fluid (9); an inner wall of the working cylinder (6) is provided with piezoelectric ceramic (8); a working gap (7) is formed between the piezoelectric ceramic (8) and the piston (12); the working gap (7) is in communication with the first cavity and the second cavity; and one side of the working gap (7) is provided with a magnetic field generation device, meeting the requirement for vibration control for civil works under the action of an earthquake. Further disclosed is a control method for the dualextruding, piezoelectricity and magnetorheological composite and intelligent damper.
