Description

A kind of two-dimensional magneto-rheological vibration damping pipe clamp
Technical field
The present invention relates to a kind of vibration damping pipe clamp, and in particular to one kind damping and the adjustable two-dimentional vibration damping pipe clamp of rigidity, is applicable In the pipe-line system that hydraulic drive, liquid are conveyed, pipeline vibration energy, the vibration of control piper are consumed.The present invention can also be pushed away Extensively into bear vibration control field.
Background technology
Hydraulic Power Transmission System, using quite varied, is Aeronautics and Astronautics, vehicle, ship in the every field of national economy And important power supply system in the field such as engineering machinery.Hydraulic Power Transmission System operationally, due to dynamic power machine motion With the reason such as fluid pressure pulse in pipeline, it will usually cause the high vibration of pipeline, and cause connecting line or connection along band The vibration of device, so as to substantially reduce the transfer efficiency of pipeline, has a strong impact on the service behaviour of hydraulic system.Pipeline vibration can add The abrasion of acute machinery, the junction such as particularly various weld seams, pipeline support is subjected to repeatedly the stress of alternation, make pipeline by Additional fatigue load, promotes the formation and extension of fatigue crack, causes pipe joint to release, and even results in fluid pressure line and breaks Split, the damage of pipeline fixed component, cause fluid pressure line to fail, directly affect the safe and stable operation of hydraulic transmission equipment.
At present, conventional pipeline oscillation damping method is damping material to be filled in pipeline installation region, from Flexible pipe fitting, installation Shock absorber, overstriking pipeline size, using damped sleeve, install accumulator additional, entered using passive control methods such as Active Noise Control technologies Row vibration damping, and passive damper has the shortcomings that big volume, damping and rigidity are fixed, it is impossible to meet the need of pipeline vibration damping control Will.
Pipe clamp is an important part in hydraulic system, for fixing pipe fitting.MR damper is a kind of Excellent semi-automatic control device, big with controling power, damping and rigidity adjustable extent are wide, and thermal adaptability is strong, response speed It hurry up, low power consumption and other advantages.Magnetic converting technique is combined with pipe clamp, and is controlled by by Intelligent Control Strategy, it is possible to achieve Vibration to pipeline in broader vibration frequency range is controlled and weakened, the effective biography for suppressing vibration in pipeline Broadcast.
The content of the invention
It is an object of the invention to provide the adjustable two-dimensional magneto-rheological vibration damping pipe clamp of one kind damping, based on MR damper Shearing valve type mode of operation, the amplitude and frequency vibrated using 3-axis acceleration sensor signal piping, according to the vibration of pipeline The size of situation regulation field coil current changes the power in magnetic field, so that change damping and the rigidity of magneto-rheological vibration damping pipe clamp, Weaken propagation of the vibration in fluid pressure line, and certain effectiveness in vibration suppression is remained in that in the case of system cut-off, effectively carry High Hydraulic Power Transmission System job stability and security.
The present invention designs magnetorheological damping vibration-proof structure in pipe clamp, adjustable using the damping and rigidity of MR damper Characteristic, the vibration to pipeline of damping and rigidity that MR damper is adjusted by changing damper magnetic field intensity controls System, consumes pipeline vibration energy to greatest extent, and propagation of the damping vibration in pipeline or attachment means significantly is reduced because of vibration And the noise and mechanical wear produced, fluid structure interaction in pipeline is effectively inhibited, weakens the pressure fluctuation of fluid in pipeline； The shortcomings of big traditional passive damper volume, damping and rigidity are fixed is overcome, while based on magnetorheological semi- active control system System has that energy consumption is low, it is big to exert oneself, fast response time, simple in construction, damping force continuously adjustabe, it is easily controllable the characteristics of, overcome Active control device is costly, energy consumption is big and the complicated shortcoming of device, and in the state of system loses power supply supply, still Certain damping force can be kept, is functionally worked on as passive damper, will not occur system crash accident, have Higher-security and reliability；Magneto-rheological vibration damping pipe clamp is consistent substantially with conventional pipe clamp in height, can directly replace liquid Press traditional pipe clamp in transmission system or fluid delivery system, it is not necessary to rearrange pipe-line system.
