摘要
基于MATLAB开发海洋立管涡激振动数值模拟系统NSVIV 1.0,系统采用尾流振子模型模拟外流对立管结构的作用,考虑内流对立管结构的影响,对立管的涡激振动动力响应和疲劳寿命进行预测分析。系统界面简洁清晰,使用方便,适用于顶张力立管,为进一步集成功能齐全的海洋立管设计分析软件打下基础。
Numerical Simulation System of Vortex-Induced Vibration of Marine Riser(NSVIV 1.0) based on MATLAB is developed.Wake oscillator model is used to simulate the effect of external fluid on the riser and the effect of the internal flowing fluid on the riser is considered.VIV dynamic responses and fatigue life of riser is predicted and analyzed.The interface of system is concise,clear,easy to use and suitable for TTR,and lays the foundation for developing more full-featured design and analysis software for marine riser.
