Problems solved by technology

However, during the working process of the damper, the traditional floating piston-spring compensation device is prone to the problem that the magnetorheological fluid in the working chamber leaks into the volume compensation chamber or the air in the volume compensation chamber escapes into the working chamber of the damper. It will lead to the formation of air bubbles and voids in the working chamber, which will affect the actual working performance of the single-rod magnetorheological damper

Embodiment Construction

[0024] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like figure 1 As shown, the magneto-rheological damper of the volume compensation separated single rod of the present invention includes a working chamber of the damper and a volume compensation chamber. The working chamber of the damper is surrounded by the outer cylinder of the damper 8, the floating plug 10, and the top cover plate 2; in the working chamber there is a piston composed of a piston head 9 and a piston rod 1, of which there is a piston head with a depth of 6-10mm The inside is wound with an enameled wire 6 with a diameter of 1mm, and the enameled wire 6 runs through the piston rod 1 to connect with the external power supply; the outside of the enameled wire 6 is sealed with 2-3mm epoxy resin 7; the magnetorheological fluid 4 fills the working chamber of the damper The remaining space inside; the top c...

Abstract

The invention discloses a volume compensation isolation type single rod magneto-rheological damper. The damper comprises a single rod magneto-rheological damper working cavity and a volume compensation cavity; the damper working cavity is encircled by a damper outer cylinder barrel (8), a floating plug (10) and a top sealing cover plate (2); the working cavity internally contains a piston and magneto-rheological fluid (4); the piston consists of a piston head (9) and a piston rod (1); the volume compensation cavity is encircled by the damper outer cylinder barrel (8), the floating plug (10) and a bottom sealing cover plate (16); a prepress high performance spring (12) is placed in the encircled cavity which is filled with high grade silicon oil (13); the upper end of the prepress high performance spring (12) is connected to the floating plug (10), and the lower end is connected to the bottom sealing cover plate (16); a porous rubber block (15) wrapping air is placed in the prepress high performance spring (12); the lower end of the porous rubber block (15) is connected to the bottom sealing cover plate (16) and does not make a contact with the prepress high performance spring (12), and normal working performances of the single rod magneto-rheological damper are ensured.

Description

technical field [0001] The invention relates to a single-rod magneto-rheological damper which can be used in the fields of civil engineering, machinery and aviation, in particular to a volume-compensated isolated single-rod magneto-rheological damper. Background technique [0002] Strong earthquakes and strong winds can lead to damage or even collapse of civil structures. How to reduce the dynamic response of structures with economical, efficient and reliable measures is a challenging international problem. Structural vibration control is a new type of anti-seismic vibration reduction technology. Specifically, control components and control devices are attached to the structure, and a set of control forces are passively or actively applied to the structure when the structure vibrates, reducing or suppressing the vibration of the structure. Dynamic response to meet the requirements of structural safety, usability and comfort. At present, structural vibration control devices ...
