Description
Technical field
The utility model belongs to construction project technical field, is related to the drum centrifuge in a kind of geo- textile technique experiment
Vibration absorber.
Background technology
Geo- textile technique is tested, and is that the model of diminution is placed in the centrifuge of rotation at a high speed, is utilized artificial centrifugal force
The body force that model is received is improved in field, and compensation model reduces the stress loss caused, to reach the stress state consistent with prototype,
Prototype mechanical characteristic can be reproduced, is the important method for studying geotechnical engineering problems, there is spy relative to other 1g model experiments
Different superiority.The important component tested as geo- textile technique, during drum centrifuge model experiment, because high speed is revolved
Turn, it is necessary to which strict guarantee dynamic balancing, eliminates out-of-balance force.Usual way is：Model and counterweight are fixed in bulging groove, along centrifugation
Machine formed symmetrical is placed, and model, counterweight and axis is on same straight line, reaches the system shape that model and counterweight are constituted
Heart position falls the purpose on axis.But due to there is operating error and model deformation movement, it is impossible to fully meet balance and require,
Cause to produce vibration in experimentation.Vibration damages larger to centrifuge service life, and to the personal safety of experimenter
There is potential threat, tested especially for high-g level, the imbalance of very little will cause vibration to exceed limit value, during experiment is forced
Only, it significantly limit the use function of centrifuge.However, currently without a kind of vibration absorber, can realize in drum-type centrifugation
Machine continuously under conditions of operation, adjusts poised state, it is ensured that centrifuge experiment is persistently carried out.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model be to provide one kind can on the premise of centrefuge experiment is persistently carried out,
Realize the device of fine setting vibration-damping function.
The technical solution of the utility model：
A kind of drum centrifuge vibration absorber, including storage box 1, flowing water Valve 2, inlet valve 3, fixing device 4 and distant
Micromachine 5 is controlled, the side of storage box 1 is provided with flowing water Valve, and the conveyer belt of remote control micro motor 5 is enclosed on flowing water Valve 2, passed through
The direction for controlling conveyer belt to rotate, realizes the folding of flowing water Valve 2；The upside of storage box 1 is provided with inlet valve 3, for retaining
Water filling in box 1；Centrifuge report control platform is fixed on by fixing device 4；
Described flowing water Valve 2 is changeover valve.
The beneficial effects of the utility model：
1) by remote control can real time remote manipulate flowing water Valve, can Therapy lasted carry out on the premise of, realize micro-
Adjust and reduce the function of shaking.
2) the utility model is simple in construction, easy to operate, can conveniently be applied to drum centrifuge model experiment.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model.
Fig. 2 is layout drawing of the present utility model.
In figure：1 storage box；2 flowing water Valves；3 inlet valves；4 fixing devices；5 remote control micro motors；6 protective covers；7 drums
Groove；8 axis；9 report control platforms；10 models；11 counterweights.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with technical scheme (and accompanying drawing).
Drum centrifuge vibration absorber includes storage box 1, sideways provided with flowing water Valve 2, flowing water Valve 2 and remote control micro electricity
Machine 5 is connected；Storage box 1 is provided with fixing device 4, and storage box 1 is fixed on drum centrifuge report control platform 9 by fixing device 4；
The upside of storage box 1 is provided with inlet valve 3.
The application method of drum centrifuge vibration absorber, step is as follows：
1) in the centrefuge experiment preparatory stage, beforehand through inlet valve 3 to the water filling of storage box 1, until filling it up with, water inlet is closed
Valve 3.Storage box 1 is fixed on centrifuge report control platform 9 by fixing device 4, two storage boxes 1 are symmetrically arranged in centrifuge
The both sides of axis 8.
2) it is 2a, 2b by the numbering of flowing water Valve 2.After centrefuge experiment starts, g values gradually increase, if occurring in experimentation
Vibration, remote controller opens flowing water Valve 2a, flows out water, if vibration reduces, persistently opens valve, until vibration subtracts
As low as experiment allows within oscillating region, closes flowing water Valve 2a；If vibration goes up not down, flowing water Valve 2a is closed, is opened
Flowing water Valve 2b, flows out water, and vibration is gradually reduced, until vibration is reduced within experiment allowed band, closes flowing water Valve
2b。
