An intelligent magnetorheological damping pipe clamp

Abstract

The invention discloses an intelligent magneto-rheological vibration reduction pipe clamp. A pipe clamp upper shell and a pipe clamp lower shell are matched to form a cavity, an inner pipe clamp is positioned in the cavity, and the cavity is also provided with an inlet and an outlet through which a pipeline enters and exits. The intelligent magneto-rheological vibration reduction pipe clamp further comprises a magneto-rheological damper, a displacement sensor used for detecting the pipeline displacement information and a controller used for calculating the working current of the magneto-rheological damper. The inner pipe clamp is connected with the pipe clamp upper shell and / or the pipe clamp lower shell through the magneto-rheological damper, the displacement sensor and the controller arefixed on the pipe clamp upper shell and / or the pipe clamp lower shell, the displacement sensor is in signal connection with the controller, and the controller is in signal connection with the magneto-rheological damper. According to the present invention, the high integration of a magneto-rheological technology, an embedded control system and the pipe clamp can be achieved, the pipe clamp has theadvantages of being continuously adjustable in damping force, high in response speed, high in reliability, low in energy consumption, wide in adaptability and the like, and the pipe clamp can still serve as the passive control equipment to work under the condition that no external energy is supplied.

Description

technical field [0001] The invention belongs to the technical field of pipeline vibration reduction, and relates to a pipeline vibration reduction device, in particular to an intelligent magneto-rheological vibration damping pipe clip that can automatically adjust the damping force, and is suitable for pipeline systems for fluid transmission. Background technique [0002] The pipeline system is an important carrier of hydraulic transmission, fluid transportation and energy transmission, and is widely used in ships, submarines, aerospace, water supply and drainage and other fields. In the pipeline system, the impact of the pressure pulsation caused by the flow rate and pressure change of the fluid medium on the pipe wall will cause pipeline vibration. In addition, the rotating machinery such as pumps and motors will generate vibration due to rotor imbalance and other reasons and transmit it to the pipeline system. middle. The vibration of the pipeline will cause pipeline fat...

AI Technical Summary

Problems solved by technology

The vibration of the pipeline will cause pipeline fatigue, loose fasteners, damage to instruments and meters, and even cause leakage of fluid media in the pipeline, which is a huge safety hazard for the hydraulic system

[0003] The pipe clamp fixes the pipeline on the base. The existing pipe clamps usually increase damping by adding rubber or springs, which have poor durability and poor vibration damping effect
