Multilayer squeezing type giant electro-rheological fluid damper

Abstract

The invention discloses a multilayer squeezing type giant electro-rheological fluid damper. The multilayer squeezing type giant electro-rheological fluid damper comprises an inner core and an outer shell. The inner core comprises an upper insulating sleeve, a lower insulating sleeve, positive electrodes and a shaft. The shaft is sleeved with the positive electrodes. The upper insulating sleeve andthe lower insulating sleeve are fixed to the two ends of the shaft correspondingly and squeeze and fix the positive electrodes between the upper insulating sleeve and the lower insulating sleeve. Theouter shell comprises an upper end cover, a lower end cover and a closed shell for negative electrodes. The center of the upper end cover is provided with a center hole. The negative electrodes are fixed between the upper end cover and the lower end cover. The positive electrodes and the negative electrodes are overlapped in a staggered mode. Certain gaps are reserved between the positive electrodes and the negative electrodes. The upper end cover and the lower end cover are fastened together. Moreover, the multilayer squeezing type giant electro-rheological fluid damper is provided with an electro-rheological fluid inlet device. The multilayer squeezing type giant electro-rheological fluid damper provided by the invention is installed on a device needing vibration attenuation and supplies controllable high voltage to the positive electrodes and the negative electrodes. Changes of voltage are controlled through a computer (or other control equipment) as required, then controllable damping can be generated, and the purpose of vibration attenuation is achieved.

Description

Technical field [0001] The invention relates to a giant electrorheological fluid damper, in particular to a multilayer squeeze type giant electrorheological fluid damper. Background technique [0002] Electrorheological fluid is a suspension formed by micron-sized polarizable solid particles dispersed in a low-viscosity non-polar insulating solvent. When no electric field is applied, the properties of electrorheological fluids are similar to those of ordinary Newtonian fluids; and once an electric field is applied, the fluid properties of the electrorheological fluids will instantly change sharply. The rheological properties change with the intensity of the applied electric field, and the apparent viscosity is orders of magnitude. The increase of, shows the nature of a solid, and its shear strength increases with the intensity of the electric field. This "liquid-solid" transition is reversible. Electrorheological fluids have controllable flow characteristics, viscosity character...

Problems solved by technology

But there is not yet a mature giant electrorheological fluid damper working in squeeze mode. Therefore, there is an urgent need for a multi-layer squeeze giant electrorheological fluid damper to fill the gap of the squeeze mode of the electrorheological fluid damper. blank
