Embodiment Construction
[0051] The present invention will be further described in detail below with reference to the accompanying drawings.
[0052] The purpose of this invention is to:
[0053] 1. In the VIV analysis of the deepwater riser, the downstream vibration is considered, so that the analysis model and results are more consistent with the actual engineering problems.
[0054] 2. Improve the existing vortex-induced lift model, consider the influence of the fluid-structure interaction effect on the vortex-induced lift, and improve the VIV analysis accuracy.
[0055] 3. Improve the calculation model of the existing vortex discharge frequency so that it is not only applicable to the locked area, but also to the non-locked area.
[0056]4. Using the time domain analysis method, the maximum amplitude of the riser VIV and its stress and fatigue damage can be analyzed intuitively.
[0057] 5. Calculate the stress by using the actual structure of the riser (tube-in-tube), so that the calculation of...
