Description
Technical field
Ocean engineering water pool model experimental technique field is the utility model is related to, is tried more particularly to anchoring system horizontal rigidity
Test multidirectional hierarchical loading device.
Background technology
With the increasingly reduction of landing field petroleum resources, Marine oil and gas resource is developed into current petroleum resources sustainable development
The important base and strategic measure of exhibition, Marine oil and gas resource exploitation become important Environment Science.Floating structure system conduct
One of basic facilities of Marine oil and gas resource exploitation, its performance has decisive work to the security development of Marine oil and gas resource
With water pool model experiment is forecast and the effective means for studying ocean structure physical performance, particularly to new floating structure system
Study on hydrodynamic performance, model test is even more essential instrument.
Float structure is usually positioned using anchoring system, and anchoring system can ensure work of the float structure in external load
Moved within the specific limits under.Research shows that the movement of the horizontal rigidity and float structure of anchoring system is closely related,
The horizontal rigidity of anchoring system refers under the action of external force dead load, the relation curve of float structure displacement and stress.In order to
Ensure that the motor imagination result of model test is close with legitimate reading, it is necessary to designed before model test formally starts
The horizontal rigidity of model anchoring system measure and check.Since anchoring system is only to the three degree of freedom on horizontal plane
(surging, swaying and head shake) has large effect, when carrying out the horizontal rigidity experiment of whole anchoring system, it usually needs examine
Consider several different Impact directions, such as vertical and horizontal, or along single mooring line direction and along between two mooring lines
Direction, during experiment the selection in direction must be determined according to the actual requirement of different anchoring systems.
The anchoring system horizontal rigidity of prototype can be very easily calculated by software.During calculating,
Apply constant external force load step by step along in some horizontal free degree of floating body, structure is produced certain offset, obtain structure
Stress, be depicted as offset-load curve, i.e. anchoring system horizontal rigidity curve.During model test, usually it is also required to
The displacement loading of one direction, more grades is carried out to model, then obtains offset-load curve.But it should be noted deviating
During need to ensure in addition to the free degree that measures is needed there is no any displacement in other frees degree, otherwise measurement obtains
Heaving pile pulling force can include the component of power in other corresponding frees degree, cause measurement result inaccurate.
In existing modeling techniques, the mode of generally use weight loading realizes the offset of physical model, will
Floating structure and its mooring and riser systems are installed in pond, are gently restricted through pulley by one and are connected with model, are measured
Model produces static shift therefrom.By varying the size of horizontal applied force, multiple corresponding offsets are obtained, so as to measure
Obtain offset-load characteristic curve of anchoring system.The advantages of this method, is that principle is simple, easy to implement.Its shortcoming is：
(1) light rope has stronger nonlinear characteristic used by, in the case of weight is less, it is believed that light rope tool
Linear characteristic, its displacement error can also carry out appropriate amendment；But with the increase of weight, the non-linear gradual increasing gently restricted
By force, the displacement error of measurement will gradually increase, and cause measurement result mistake；
(2) gravity laod applied is acted on model by pulley, and there is larger friction work in itself for pulley
With, therefore the active force on model is applied to not exactly equal to the gravity of the weight applied；
(3) combination of light rope, pulley and weight does not ensure that stringent being produced along a direction of model deviates, model
The displacement of other frees degree can be produced during offset, so as to cause measurement error；
(4) being applied to external load on model by pulley may be therefore real with model level face there are certain angle
The horizontal loading that border is acted on model is a horizontal component of weight gravity, so as to cause measurement error；
(5) during measurement, model may produce reciprocating motion, it is necessary to longer under the action of anchoring system
Time can stablize, and measurement process is time-consuming, and measurement result is not allowed.
In short, when carrying out anchoring system horizontal rigidity displacement loading by existing technology and method, can not be quick and precisely
Ground measures displacement and stress, while the active force error that measurement obtains is larger, model test result may finally be caused to be not allowed, no
It can reflect the real motion response of prototype.
For this, it would be highly desirable to propose a kind of device, can implementation model displacement disposably precisely loaded along certain direction, with reference to mooring
Corresponding value, processing obtain the horizontal rigidity of anchoring system on cable pull-up force snesor, it will greatly improve model test
Precision, reduces the time of model test, reduces the expense of model test, and the smooth of model test is carried out with important
Meaning.
