Along with the increasing of Marine oil and gas resource exploitation dynamics with drive on the quickening of paces boldly to deep water, marine riser draw ratio by
Cumulative greatly, its residing marine environment is the most severe.When ocean current, wave flow through marine riser with certain speed, meeting exists
Marine riser afterbody produces the vortex periodically alternately come off, and coming off of vortex changes the distribution of marine riser wall stress, and
Make it present periodically change, thus cause marine riser to vibrate, i.e. vortex-induced vibration.Under lasting vortex-induced vibration effect,
Marine riser can occur fatigue damage and structural instability, and safety work and marine environment are all brought serious hidden danger.Therefore,
The suppression research carrying out vortex-induced vibration has particularly important practical meaning in engineering.
In the over half a century in past, Chinese scholars has been achieved for many stages to the study mechanism of vortex-induced vibration
Property achievement, some scholars it is also proposed the measure of multiple suppression vortex-induced vibration for Practical Project problem, these methods mainly from
Flow field control and tube performance change starts with, and flow field control is divided into again active control type and passive control type two kinds, actively controls
Type restraining device refers to utilize Sensor monitoring afterbody information of flow, sends dynamic instruction according to information after judging, introduces corresponding
The external energy of size is in flow field, thus effectively controls Vortex Shedding.Passive control the most directly to change body structure surface shape or
Additional extra means streams section to change, thus changes flow field, destroys the formation of vortex.Tube performance changes main by adjusting
The kinetic parameter of homogeneous tube road self structure, such as quality, damping, rigidity etc., thus weakens the oscillation intensity of pipeline, reduces it and shake
Dynamic amplitude.Can these several means of organic synthesis, more effectively suppression deep water marine riser vortex-induced vibration be current deep water
Oil and gas development problem demanding prompt solution.
