Description
Technical field
The present invention relates to field of ocean engineering, specifically two-way self-oscillatory device under a kind of simulation uniform flow two riser model phase mutual interference.
Background technology
Standpipe in the actual marine environment is long fine and soft property structure, can produce vortex-induced vibration under the effect of ocean current, and the structural fatigue that vibration causes or possible resonance etc. will cause great threat to the safety of marine structure.
Vortex-induced vibration is that self-excitation produces for the standpipe that is in the ocean.Because the restriction of physical size test condition is mainly studied the vortex-induced vibration phenomenon of compliant riser by model test and numerical simulation at present.Model test is divided into multistage with compliant riser, supposes each section for rigid cylinder, and cylinder is carried out forced oscillation test or self-sustained oscillation test, but with can not the forecast with unerring accuracy dynamic response of the cylinder under the true sea situation of the model test of scaling factor; Numerical simulation means then lacks the reliability of its result of calculation of verification experimental verification, and the present imperfection still of processing of the problem such as convection cell viscosity wherein.
In addition, in marine structure, exist a plurality of situations of closing on the mutual interference of cylinder phase, such as four columns of semi-submerged platform, and numerous tension legs of tension leg platform (TLP).Because influencing each other between the right cylinder, the vibration mechanism of the vortex-induced vibration of bicylindrical body or polycylinder and phenomenon are more complicated for the single cylindrical body.The researcher has carried out certain research to vortex-induced vibration excitation and the phenomenon of bicylindrical body both at home and abroad at present, finds that it almost is impossible carrying out Accurate Prediction with theory, and test is only the most effective research mode.
But, existing research device ubiquity is following not enough: (1) traditional self-sustained oscillation Pilot office is limited to the practical structures performance of riser segmented model, can only record the vortex-induced vibration response of the standpipe with set structural behaviour parameter, reduced universality, to consume the plenty of time and change standpipe, spring, damper etc., delay the test progress; (2) can only make segmented model with set cycle forced vibration according to the operating mode of setting, can't record segmented model really response under the incoming flow effect; (3) be difficult to simulate the special sea situations such as two cylinder phases mutual interference; (4) be put to the test plant bulk restriction, the slenderness ratio of model is less, and scale effect is larger.(5) owing to the complicacy of test unit, the self-sustained oscillation of bicylindrical body is tested seldom, and the test of the vortex-induced vibration of bicylindrical on both direction is not also carried out basically.(6) can only simulate the vortex-induced vibration of single-degree-of-freedom direction, can't simulate more near the vortex-induced vibration on two degree of freedom of actual conditions.
