摘　　要：以某管架式海上养殖平台为例,研究其水动力性能和平台-系泊系统耦合时域动力响应。分析该平台的运动幅频响应因子、锚链拉力统计特性、波频振荡与二阶力特性、最大锚链拉力组成成分和运动规律等。研究发现,二阶力对系泊系统动力响应有重要影响,漂移力是决定该平台系泊系统安全性的主要因素。计算结果表明,该平台具有良好的水动力性能,系泊缆能有效限制平台运动,且其强度满足规范的要求,可供类似平台的设计和安全性评估参考。This paper takes a pipe-rack offshore aquaculture platform as the example to study the hydrodynamic performance and the coupling time-domain dynamic response of the platform-mooring system,and to analyze the response amplitude operator of the platform motion,the statistical characteristics of chain tension,the features of wave-frequency oscillation and second-order force,the composition of maximum chain tension,and the law of platform motion.It is found that the second-order force has an important influence on the dynamic response of the mooring system,and the drift force is the main factor that determines the safety of the mooring system.The results show that the platform has a good hydrodynamic performance,the mooring chains can effectively restrict the movement of the platform,and their strength can meet the requirements of the rules,which provides reference for the design and safety evaluation of similar platforms.
