A multi-cylinder linkage inner winding magnetorheological damper

Abstract

The invention discloses a multi-cylinder-barrel linked internally-wound type magneto-rheological damper. The multi-cylinder-barrel linked internally-wound type magneto-rheological damper comprises a damper outer cylinder barrel, at least two branch cylinder barrels arranged in the damper outer cylinder barrel, and push rods installed in the branch cylinder barrels. A magnetic conductive inner sleeve is connected to the inner wall of the damper outer cylinder barrel. A fixing column is arranged between the branch cylinder barrels. Each branch cylinder barrel is internally provided with one pushrod, the right end of each push rod is connected with a piston head, a winding groove is machined in each piston head, an electromagnetic coil is wound in the winding groove of each piston head, theleft end of each push rod is connected to a supporting frame, the middle of the left end of each supporting frame is connected with the right end of the corresponding piston rod, and the left end of each piston rod penetrates out of a left end cover of the damper to be fixedly connected with a left suspension lug in a threaded mode. When the electromagnetic coil is switched on, the yield stress ofmagneto-rheological liquid can be changed by adjusting the current in the electromagnetic coil so that required output damping force can be achieved, and due to combined effect of the multiple branchcylinder barrels, the output damping force of the internally-wound type magneto-rheological damper is improved.

Description

technical field [0001] The invention relates to a magneto-rheological damper, more specifically, it relates to a multi-cylinder linkage inner-winding magnetorheological damper. Background technique [0002] The magnetorheological damper is a new type of semi-active damping device based on the controllable characteristics of magnetorheological fluid. The damping device can generate resistance to movement and be used to dissipate the energy of movement; It has the advantages of simple structure, small size, easy control and low energy consumption; it is an ideal vibration isolation and anti-seismic device; it has wide application prospects in construction, machinery, military industry, etc. [0003] The traditional spring damper is used in various vibration reduction occasions, but as people's requirements for vibration reduction effect are getting higher and higher, the vibration reduction effect played by the spring damper is gradually unsatisfactory. The advent of magnetor...
