Description
Technical field
The invention belongs to ocean engineering field, measure elongated standpipe power more particularly to uniform flow outside a kind of face and ring
Should, while monitoring the experimental provision of vortex-induced vibration (VIV).
Background technology
In the presence of stormy waves stream, marine floating type works will drive catenary riser to make periodic reverse fortune in water
It is dynamic, flowed so as to produce Relative Oscillation in the standpipe direction of motion, there is " interval to flow by this vibration in excitation standpipe pendency section
The vortex-induced vibration of property ".In recent years, start largely to use catenary riser with the exploitation of deep-sea oil system, in engineering.It is deep
Standpipe in water environment can be considered elongated flexible structure, and now small deformation is theoretical is no longer applicable, and this causes the vortex-induced vibration of standpipe
Problem is more protruded, therefore is for the analysis of the overall vortex-induced vibration response characteristic under the effect of slender flexible standpipe top platform
Its key point that can be applied to engineering practice.
In the past forecast slender marine structures vortex-induced vibration harm most common method be numerical computations SHEAR7,
VIVA, VIVANA, it is this to predict that load and the method for response still have very big uncertainty so far by theoretical formula.Mesh
Before untill, be exactly model test method to one of most important method of research of flexible pipe vortex-induced vibration phenomenon.In model test
It was observed that phenomenon closer to nature truth.By the retrieval to prior art, riser model experiment typically exists
Carried out in towing ocean engineering swimmer's pool, what is had is carried out in annular water tank, what is had carries out vortex-induced vibration with towboat dragging standpipe
Test.It is published in paper " the Exper iments with a during " Applied Ocean Research (2013) " 43 is printed
Stee l catenary riser model in a towing tank " (the slender flexible standpipe model realities in towing basin
Test), the steady flow condition around standpipe is simulated by running the compartment being connected with standpipe in towing basin, pacify on standpipe
Dress miniature acceleration measuring instrument monitors the state of standpipe.Analyze this kind of measuring technology, find its not foot point be：1st, in view of dragging
The depth in pond is draged, the vortex-induced vibration of small yardstick pipe fitting can only be typically simulated, it is difficult to swashed in the whirlpool effectively carried out under real Reynolds number
Vibration-testing 2, the monitoring device under water being not easy to around arrangement standpipe, can not be adjusted when sloping wave type riser model is tested
Save standpipe shape 3, can not carry out under certain flow rate forced oscillation experiment 4, in an experiment install standpipe process it is more multiple
Miscellaneous 5, the motion of ocean platform can not effectively be simulated.
The content of the invention
