Self-induction Magneto-rheological Damping Pipe Clamp

Abstract

The invention discloses a self-induction magneto-rheological damping pipe clamp, which comprises a fixed top cover, a vertical pipe clamp, a damping rubber sleeve, a micro energy conversion unit and a fixed bottom plate. The rubber cavity of the damping rubber sleeve is filled with a magnetic rheological fluid material. The micro energy conversion unit arranges the metal coil in the damping rubber sleeve, and is wound on the outside of the magneto-rheological fluid material. Two ends of the coil are electrically connected with the MEMS vibrating electromagnetic micro power device, and when the pipeline vibrates, the MEMS vibrating electromagnetic micro power device absorbs the vibration energy of the pipeline and converts it into electric energy so as to generate a magnetic field after the coil is energized, and the magnetic rheological fluid material is cured under the action of the magnetic field, and the curing degree increases with the strength of the magnetic field, thereby changing the rigidity of the damping rubber sleeve, increasing the clamping degree to the pipeline, and finally reducing the vibration of the pipeline. In this invention, the vibration absorption vibration of the pipeline can be realized, the rigidity and clamping degree of the pipe clamp can be regulated according to the vibration degree of the pipeline, and the absorption and reuse of the vibration energy can be realized.

Description

technical field [0001] The invention belongs to the field of mechanical engineering and relates to the fixing and vibration reduction of pipelines, in particular to a self-induction magneto-rheological vibration damping pipe clamp, which is especially suitable for fixing and vibration reduction of aviation hydraulic pipelines. Background technique [0002] Pipe clamps are an indispensable component for pipe fixing and connection. It is necessary to ensure sufficient connection strength and ensure the tightness of pipe connections. The vibration effect of the existing pipe clamp is poor, and strong vibration will damage the pipeline or even cause it to break, thereby affecting the safety of the entire system. [0003] The rapid development of modern aerospace drives the development of aircraft towards large-scale and high-speed. The number of aviation pipelines of a single aircraft has also increased significantly, the aircraft pipeline system is more complex, and the space ...
