Abstract

The invention discloses a horizontal annular slot type test device for a magnetorheological material, which comprises a frame, wherein a magnetic field generating device, a shearing mechanism, a shearing strength detection mechanism, a warming and temperature detection mechanism, a lifting mechanism and a control system are arranged on the frame. Compared with the traditional test device, the horizontal annular slot type test device for magnetorheological material provided by the invention is additionally provided with the warming and temperature detection mechanism, so the device can be used for testing the influence of temperature on the magnetorheological liquid property. The three factors (temperature, magnetic field intensity and shearing strain rate) influencing the magnetorheological liquid and the change gradient of the three factors can be controlled, so the property parameters of the magnetorheological liquid can be more comprehensively detected. The shearing mechanism of the device can be used for furthest concentrating the shearing strength between a fixing ring and a shearing ring at the position of the magnetorheological liquid, thereby ensuring an accurate testing result and acquiring a better testing effect.

Description

technical field [0001] The invention relates to the technical field of magnetorheological materials, in particular to a horizontal ring groove type magnetorheological material testing equipment. Background technique [0002] Magnetorheological materials are a new type of intelligent materials, including magnetorheological grease, magnetorheological elastoplastic, magnetorheological fluid, etc., among which magnetorheological fluid is the most widely studied and applied. Magneto-rheological fluid is a suspension mixture formed by micron-sized ferromagnetic particles evenly distributed in a specific solvent. When there is no external magnetic field, the rheological properties are similar to ordinary Newtonian fluids, but it can produce The magnetorheological effect (Magnetorheological Effect MRE), that is, the apparent viscosity can increase several orders of magnitude within milliseconds, showing solid-like mechanical properties, and the shear stress and viscosity change re...
