Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Dielectric permittivity is one of the properties of dielectric materials, and changes in the type and composition of dielectric materials will change their permittivity. In the measuring container where the magnetorheological fluid is used as the capacitor medium, during the sedimentation process of the magnetorheological fluid, the content of the components of the magnetorheological fluid changes at different liquid levels, resulting in different permittivity at different liquid levels.

[0032] In the method of monitoring the sedimentation characteristics of magnetorheological fluid based on permittivity, the difference in permittivity of different liquid heights during the sedimentation process of magnetorheological fluid will be expressed as the change of capacitance of the magnetorheological fl...

Abstract

The invention relates to magnetorheological suspension sedimentation characteristic measurement, and especially relates to a capacitance monitoring device and monitoring method for a magnetorheological suspension sedimentation process. The capacitance monitoring device for the magnetorheological suspension sedimentation process comprises a magnetorheological suspension inlet (1), a base (2), an inner cylinder (3), an outer cylinder (4), a capacitor conductor pole plate (6), and a capacitance value measuring apparatus and a data processing apparatus; the inner cylinder (3) and the outer cylinder (4) are in cylindrical form and placed concentrically, in order to form a hollow circular column, the cylinder which is formed by the inner cylinder (3) and the outer cylinder (4) is arranged on the base (2), and the bottom part of a gap formed between the inner cylinder (3) and the outer cylinder (4) is arranged at a magnetorheological suspension inlet (1); multiple pairs of capacitor conductor pole plates (6) are coated on outer side of the inner cylinder (3) and the inner side of the outer cylinder (4) along the height direction of a hollow circular column, in order to form multiple capacitors, and a pair of capacitor conductor pole plates (6) at the same height are opposite; the capacitance value measuring apparatus and the data processing apparatus are connected.

Description

technical field [0001] The invention relates to the measurement of the settling characteristics of the magnetorheological fluid, in particular, a capacitance monitoring device and a monitoring method for the settling process of the magnetorheological fluid are designed. Background technique [0002] Magnetorheological fluid is an intelligent material with wide application and excellent performance. It has the advantages of high yield strength, wide damping amplitude modulation, fast response speed, good stability, and low energy consumption. Magnetorheological fluid products are widely used in bridges, buildings, etc. , vehicles, machinery and other engineering fields. [0003] After the magnetorheological fluid settles, it is prone to sedimentation and stratification, that is, the fine particles of the dispersed phase in the magnetorheological fluid settle to form a soft sedimentation base or even harden into a hard block, which affects or even loses the original performanc...
