The experimental rig of spud leg docking unit (Leg Mating Units, LMU) is simulated in the model test of chunk floating support mounting.
Background technology
Model test as Naval Architecture and Ocean Engineering field a kind of important research method, for accurate forecast ocean structure
The hydrodynamic performance of thing, reduces the risk of Attention problems operation, has great significance.
During floating support mounting, most complicated and crucially upper chunk and jacket spud leg docking and load transfer
Process.In this process, the weight of barge and drinking water are continually changing, while barge and upper chunk pass through under wind wave action
Deck support unit and intercoupling for spud leg docking unit move to transmit load, and whole process is a complicated dynamic change
Change process.So, it is necessary to accurate simulation spud leg docking unit (Leg Mating in the model test of floating support mounting
Units, LMU) device, to forecast the exercise performance and mechanical characteristic of floating support mounting system.
In actual floating support mounting, spud leg docking cell arrangement is welded on the bottom of upper chunk, and positioned at jacket
The top of spud leg.The device is mainly made up of tapered receiver, sandbox, vertical and transverse elasticity buffer unit etc..Wherein, it is tapered
Receiver has cone groove, and upper chunk can enter in spud leg docking unit in the case where cone inserts the guiding of point and be connect with it
Touch, its radius is referred to as ensureing that platform chunk inserts point motion and catching radius in the seizure radius that spud leg docks unit, floating support
Within；Vertical and horizontal elastic buffering mechanism is mainly used to buffer the collision between upper chunk and jacket；Sandbox is main
For the movement velocity of load shedding lotus transfer process middle and upper part module, it is to avoid the contact of steel to steel, it is allowed to mildly fall on most final position
Put.
The invention of the present apparatus is in order in the model test of floating support mounting, using existing resource and technology, exactly
Simulate spud leg docking cell arrangement.It is similar that the present apparatus docks cell arrangement on geometric shape with actual spud leg, meets geometry
Condition of similarity.Meanwhile, vertical and horizontal spring is respectively provided with inside spud leg docking unit, actual spud leg can be simulated to order
The stiffness characteristics of member in all directions.The level suffered by spud leg docking cell arrangement during floating support mounting can finally be measured
With the active force on vertical direction.Do not find that similar techniques are applied to the open source literature of this area by further retrieval.
Therefore, those skilled in the art is directed to developing a kind of model for ocean platform upper strata chunk floating support mounting
The experimental rig that spud leg docking unit spud leg docks unit is simulated in experiment.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of suitable for floating support
The spud leg docking cell arrangement of model test, including fixed support, horizontal buffer, cone tank, the slotting point of taper and strain are installed
The component sensor of formula three, the horizontal buffer is connected with the fixed support, the cone tank simultaneously with the fixed support
With horizontal buffer connection, the sharp and described component sensor of strain-type three connection is inserted in the taper, and point is inserted in the taper can
The cone tank is inserted, the fixed support is used to fixing and supporting whole spud leg docking cell arrangement.
Further, the cone tank and the taper insert point and meet geometric similarity, several in actual floating support for simulating
What is constrained.
Further, the cone tank vertical direction sets uprighting spring, the uprighting spring two ends respectively with it is described solid
Fixed rack and cone tank contact.
Further, the uprighting spring is connected in series by the spring of two sections of different-stiffness, by changing the vertical bullet
The stroke of spring provides vertical force.
Further, the horizontal buffer include horizontal spring and horizontal cylinder, the horizontal spring two ends respectively with
The cone tank and horizontal buffer contact.
Further, the cone tank and taper are inserted point and are made up of metallic aluminium, and metallic aluminium has some strength.
Further, the component sensor of strain-type three is fixed on the taper and inserted on point, by changing its stroke
Measure horizontal lateral force, horizontal longitudinal force and the vertical force suffered by the slotting point of taper.
Further, the fixed support includes pedestal frame and vertical cylinder, and the pedestal frame is is used vertical cylinder
Bearing-surface, the vertical cylinder welding is on the pedestal frame.
Further, the horizontal buffer is 4, is distributed in around vertical cylinder, between each horizontal buffer
Angle is 90 °.
In model test, the slotting point of taper docks cell arrangement with spud leg and contacts with each other and collide, and passes through the position that point is inserted in taper
The deformation for causing horizontal spring and uprighting spring is moved, so that the active force on horizontally and vertically direction is produced, to constrain upper group
The motion of block.Meanwhile, the component sensor of strain-type three being fixed on the slotting point of taper, which can be measured, obtains spud leg docking unit dress
The active force on horizontally and vertically direction put.
As shown in Fig. 3 spud leg docking unit inserts sharp interaction sketch with taper.Because barge is transported in floating support mounting
It is dynamic smaller, it is believed that the central axis direction of spud leg docking cell arrangement is perpendicular to horizontal plane.Therefore can be according to spud leg pair
Spud leg docking model of element is divided into three kinds of situations by the relative position that point is inserted in order member and taper：
(1) in d1 ＞ V, insert point with LMU do not have it is any contact, therefore do not have interaction force.
(2) in d1≤V, insert sharp and LMU and completely attach to, upper chunk is small size in the case where inserting the constraint of point and each spring
The motion of degree.
(3) in 0 ＜ d1≤V, horizontal force is together decided on by d1, d2 and cone bevel angle.As shown in figure 3,
When d1 is close to 0, horizontal force when d2=0 calculate；When d1 is close to V, horizontal force when d2=H/2 calculate, directly
The slope of line is horizontal rigidity.
The apparatus structure is simple, and definite functions, by adjusting the length of different-stiffness spring, can accurately simulate spud leg pair
The nonlinear stiffness characteristic in three directions of order element apparatus, and accurately measurement obtains the active force on three directions, more accurately
Simulation and forecast ocean platform floating support mounting.
