Embodiment Construction

[0017] The present invention will be further described in conjunction with the accompanying drawings.

[0018] As shown in the accompanying drawings: the magnetorheological fluid anti-sedimentation method is that the cylinder of the magnetorheological damper is provided with inlet and outlet ports, and a self-circulation device is arranged between the inlet and outlet ports. When the magnetorheological damper is standing still for a long time, the self-circulation device can be started regularly to make the magnetorheological fluid circulate through the self-circulation device to ensure the long-term uniformity and stability of the magnetorheological fluid.

[0019] Described self-circulation device is mainly made of micro solenoid valve 2, micro pump 5, and micro solenoid valve 2 and micro pump 5 are respectively connected with the controller 3 on the magneto-rheological damper 1; One end of micro solenoid valve 2 passes pipeline 7 It is connected to the liquid outlet on the ...

Abstract

The invention discloses a method for preventing settlement of magneto-rheological fluid of a magneto-rheological damper. The cylinder of a magneto-rheological damper (1) is provided with a fluid inlet and a fluid outlet, and a self-circulating device is arranged between the liquid inlet and the liquid outlet. When the magneto-rheological damper is kept static for a long time, the self-circulating device is started regularly, so that the magneto-rheological fluid can circulate through the self-circulating device, thereby ensuring the long-term uniformity and stability of the magneto-rheological fluid. The self-circulating device is mainly composed of a micro solenoid valve (2) and a micro pump (5), wherein the micro solenoid valve (2) and the micro pump (5) are respectively connected to a controller (3) on the magneto-rheological damper (1); one end of the micro solenoid (2) is connected to the fluid outlet on the cylinder of the magneto-rheological damper through a pipeline (7), the other end is connected to the micro pump, the micro pump (5) is connected to the fluid inlet on the cylinder of the magneto-rheological damper through the pipeline. The invention is applicable to the magneto-rheological damper kept static for a long time, and broadens the application prospects of the magneto-rheological damper.

Description

technical field [0001] The invention relates to the field of engineering vibration reduction (vibration), and mainly relates to a magnetorheological fluid anti-settling method of a magnetorheological damper. Background technique [0002] Magneto-rheological damper is a variable damping controller with excellent performance. It has the advantages of wide adjustable range of damping force, rapid response and less energy required. It is an ideal device for semi-active control of structures. In the field of civil engineering, semi-active control based on magneto-rheological dampers has been widely used in wind-induced and seismic response control of high-rise and bridge structures. [0003] At present, the sedimentation problem of magnetorheological fluid has not been well solved, especially after long-term standing, the magnetic particles are prone to serious sedimentation and form hard lumps or cakes, thus losing the function of use. The sedimentation stability of magnetorheo...
