Abstract

The invention discloses a two-way independent valve type magneto-rheological damper. The magneto-rheological damper comprises a cylinder barrel, a left end cover, a right end cover and a valve body mechanism, wherein the left end cover and the right end cover are arranged at the end part of the cylinder barrel, the valve body mechanism is arranged in the cylinder barrel and can reciprocate in the axis direction of the cylinder barrel, and the valve body mechanism comprises a piston rod, a piston outer sleeve, a limiting baffle which is arranged at the left end of the piston outer sleeve, a valve element which is arranged in the piston outer sleeve and connected with the piston rod, and a left valve body assembly which is arranged between the limiting baffle and the valve element. According to the technical scheme, the two-way independent valve type magneto-rheological damper combines a passive damper and a semi-active damper, the problems that the output force value of the passive damper is single and the semi-active damper depends too much on a control algorithm are solved, meanwhile, the problem that actual working conditions have different requirements for compression force values and restoring force values is solved, and the adjusting range of the required damping force can be effectively expanded on the basis of the passive damper.

Description

technical field [0001] The invention relates to the field of magnetorheology, in particular to a two-way independent valve magnetorheology damper. Background technique [0002] Among the currently commonly used dampers, it is difficult for the passive damper to adjust the output force value according to the actual working conditions; the traditional symmetrical magneto-rheological damper is difficult to meet the demand for damping force of the actual working conditions under the conventional control algorithm, and the accurate The control algorithm is more complicated, which will greatly increase the cost. [0003] For this reason, this paper proposes a new type of damper that combines passive dampers and magneto-rheological semi-active dampers. On the basis of passive dampers, semi-active characteristics and advantages are added, and the output force of passive dampers is expanded. Value range, while using a two-way independent control valve structure, can greatly reduce t...
