Abstract

The invention discloses a novel intelligent shock absorber integrating multilayer magnetorheological elastomers with a magnetorheological damper. The shock absorber comprises the magnetorheological damper and a variable stiffness device comprising the multilayer annular magnetorheological elastomers and magnetorheological elastomer magnet exciting coil windings mounted between the multilayer annular magnetorheological elastomers respectively, wherein the magnetorheological damper comprises a cylinder barrel; the cylinder barrel is connected to the top end of the shock absorber through a spring; a piston plate is arranged in the cylinder barrel; a piston rod is fixedly connected to the lower side of the piston plate; the other end of the piston rod penetrates out of the cylinder barrel and is fixed at the bottom end of the shock absorber; a magnetorheological damper magnet exciting coil winding is wound on the side wall of the piston plate; the cylinder barrel is filled with a magnetorheological fluid; a damping device is connected with the variable stiffness device in parallel or in series. Due to the integration of the multilayer magnetorheological elastomers and the magnetorheological damper, the stiffness and damping change range of the shock absorber is relatively large, a relatively good shock absorption effect can be achieved, and the shock absorber is compact in structure.

Description

technical field [0001] The invention relates to the technical field of shock absorbers and intelligence, in particular to an intelligent shock absorber integrating a multilayer magnetorheological elastomer and a magnetorheological damper. Background technique [0002] Vibration can cause a series of problems, such as the fracture and failure of mechanical parts caused by vibration, the fracture and collapse of bridges, and the deterioration of the working environment of workers. In view of this, various shock absorbers have been used to reduce vibration and energy dissipation in industries such as aerospace, aviation, military industry, guns, automobiles, construction, bridges, and railways. The passive shock absorber consisting of a spring with fixed stiffness and a damper with fixed damping has become the main form of vibration reduction in the field of vibration reduction. However, with the improvement of people's requirements for vibration reduction, passive shock absor...
