Abstract

A novel intelligent shock absorber integrating multilayer magnetorheological elastomers and magnetorheological dampers, including a magnetorheological damper, the magnetorheological damper includes a cylinder, and the cylinder is connected to the damper through a spring. The top of the shock absorber, the inside of the cylinder is provided with a piston disc, the lower side of the piston disc is fixedly connected with a piston rod, and the other end of the piston rod passes through the cylinder and is fixed at the bottom of the shock absorber. The side wall is also wound with magnetorheological damper excitation coil windings, and the inside of the cylinder is filled with magnetorheological fluid; A variable stiffness device composed of a magnetorheological elastomer excitation coil winding between the elastic bodies, the damping device and the variable stiffness device are connected in parallel or in series, and the shock absorber integrates the magnetorheological damper and the magnetorheological elastic The body has a large range of stiffness and damping, which can achieve better vibration reduction effect, and its structure is compact.

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...
