Finite Particle Method Analysis of Snap Behavior in Catenary Mooring Lines of Deep-Sea Floating Wind Turbines Under Combined Wave and Current Conditions
摘要
Abstract
This study employs the Finite Particle Method(FPM)to conduct an in-depth investigation of the snap behavior in catenary mooring lines of deep-sea floating wind turbines under combined wave and current conditions.A nonlinear analysis method for mooring lines considering both geometric and material nonlinearities was established.The dynamic tension variation and snap behavior of mooring lines under different wave amplitudes,frequencies,and tangential drag coefficients were simulated and analyzed.The results indicate that snap behavior typically initiates at the upper end of the mooring line and gradually affects the middle and lower sections as the wave excitation continues and intensifies.Wave amplitude and frequency significantly influence the dynamic tension and snap behavior of the mooring lines,with larger wave amplitudes and higher frequencies leading to more intense snap occurrences.The increase in tangential drag coefficient reduces the movement amplitude of the mooring lines,thereby decreasing the occurrence of snap behavior and enhancing the safety and stability of the mooring system.This study provides theoretical support and technical reference for the design and optimization of mooring systems for floating wind turbines.关键词
