Extrusion mode giant electrorheological fluid damper

Abstract

The invention discloses an extrusion mode giant electrorheological fluid damper which comprises a support, a container and a connecting structure. The support comprises a bottom plate, guide shafts and a top plate, the guide shafts are vertically fixed to the bottom plate, and the top plate is slidably arranged on the guide shafts. The container comprises a container body and two spiral spring pieces coaxially arranged in the container body, the container body is fixed to the bottom plate, the bottoms of the two spiral spring pieces are fixed to the bottom of the container, the two spiral spring pieces are not in contact with each other and are spaced by 180 degrees, the container body is used for containing giant electrorheological fluid, and the two spiral spring pieces are used for being connected with a positive electrode and a negative electrode respectively. The top of the connecting structure is fixedly connected with the top plate, and the bottom of the connecting structure is fixedly connected with the tops of the two spiral spring pieces. Compared with the prior art, the extrusion mode giant electrorheological fluid damper can output a stable and controllable damping force with a high giant electrorheological fluid utilization rate under the conditions of small size and no dependence on additional rigid elements.

Description

technical field [0001] The invention relates to the technical field of vibration dampers, in particular to a squeeze mode giant electrorheological fluid damper. Background technique [0002] Electrorheological fluid is a new type of intelligent material, which exhibits a special rheological effect, that is, when there is no electric field in the liquid, the particles inside the electrorheological fluid present a disordered distribution, and appear as Newtonian fluid macroscopically; when applied in the liquid When the electric field is applied, within a few milliseconds, the particles inside the liquid are polarized and arranged in an orderly manner, macroscopically changing from a Newtonian fluid to a solid-like state; when the electric field in the applied liquid is set to zero, the particles inside the liquid will return to their original state. Disordered distribution, changing from solid-like form to Newtonian fluid, the whole process is reversible and the response spee...

AI Technical Summary

Problems solved by technology

Although the existing giant electrorheological fluid damper is superior to the traditional damper, there are still shortcomings, such as a multi-layer extrusion giant electrorheological fluid damper proposed by the patent No. CN 107687494, the damper is listed by Superposition connects multiple electrodes to the cylinder wall, which increases the instability of the equipment, and there are hidden dangers of liquid leakage and electric leakage

Not only that, the existing giant electrorheological fluid damper has the disadvantages of low damping utilization rate, complex structure, and cannot be used alone
