非线性波浪载荷与单点系泊船舶的流固耦合问题在海洋工程领域备受关注。本文基于光滑粒子流体动力学（SPH）方法，结合集中质量法系泊求解技术，建立了基于GPU加速技术的三维耦合水动力学模型，数值模型通过对比实验结果验证了计算精度与稳定性。在此基础上，本文将该模型应用到非线性波浪载荷与单点系泊船舶的耦合作用过程。研究结果表明，短周期波浪加剧纵摇运动并引发高频系泊张力峰值，与长周期波浪的峰值差值可达200 N；特别在横浪工况下，持续波浪激励导致纵摇角持续累积并伴随明显甲板上浪现象，存在倾覆风险。研究结果为海洋工程中系泊系统的优化设计与单点系泊船舶在波浪条件下的水动力学性能评估提供高效可靠的数值分析模型。
The fluid-structure coupling problem of nonlinear wave loads and single-point moored ships has attracted much attention in the field of ocean engineering. In this paper, a three-dimensional coupled hydrodynamic model based on GPU acceleration technology is established based on the smooth particle hydrodynamics (SPH) method, combined with the centralized mass method mooring solution technology, and the numerical model is verified by comparing the experimental results with the computational accuracy and stability. On this basis, this paper applies the model to the coupling process of nonlinear wave loads and single-point moored ships. The results show that the short-period wave intensifies the longitudinal motion and triggers high-frequency mooring tension peaks, and the peak difference with the long-period wave can be up to 200 N. Especially in the case of transverse wave conditions, the persistent wave excitation leads to the accumulation of longitudinal rocking angle and accompanied by the phenomenon of obvious deck wave, which is a risk of capsizing. The results of this study provide an efficient and reliable numerical model for the optimization of mooring systems in ocean engineering and the evaluation of the hydrodynamic performance of single-point moored ships under wave conditions.
