On pipe clamp, easily cause pipe clamp and loosen or fracture, and due to the interaction of pipeline Yu pipe clamp so that pipeline
Tired and wear-out failure is concentrated mainly near pipe clamp.In order to reduce pipeline vibration and reduce pipeline vibration to pipe clamp
Impact, on pipe clamp, generally increase rubber or the elastic damping pad of plastic foam material, or consolidating at pipe clamp
Determining to assemble on bolt shock-absorbing spring, both the above oscillation damping method belongs to passively control, and effectiveness in vibration suppression is unsatisfactory.
MR damper is a kind of excellent semi-automatic control device, has control power big, and damping and rigidity can
Adjusting wide ranges, thermal adaptability is strong, fast response time, low power consumption and other advantages.By magnetic converting technique and pipe clamp phase
In conjunction with, and be controlled by by Intelligent Control Strategy, it is possible to achieve to pipeline in broader vibration frequency range
Vibration be controlled.
