摘　　要：针对极端海况条件下,对海上核电平台的软刚臂式单点系泊系统进行了初步设计研究。采用我国渤海海域万年一遇海况条件,同时考虑极限海况下的风、浪、流以及冰载荷不同组合工况,对该系泊系统进行载荷及运动响应计算分析,建立了系泊时变刚度数值计算模型;绘制了系统的刚度特性曲线,最后,对该设计系统进行优化设计分析,包括:各设计参数敏感性分析、系泊力特性分析、低频共振特性分析、运动特性分析和防碰撞余量分析等。综合以上分析,最终确定该系泊系统在不同海况重现期标准下的主尺度、结构重量和重心以及载荷与运动响应。该文软刚臂式单点系泊系统的设计方法及其优化分析过程,对单点式系泊系统的选型和设计具有一定的参考意义。A primary design of soft yoke mooring system for a marine nuclear power platform in extreme sea state is introduced,and the motion and load responses of the system is calculated.An analytical solution for the motion and load response of the system is provided based on the stiffness model involving wind,wave,current and ice load in the Bohai Sea in China.Responses to JONSWAP wave spectrum are calculated with different formulas and compared each other.An optimal design of the mooring system is conducted and applied in the system analysis including design parameter analysis,mooring force analysis,low-frequency resonance analysis,motion analysis and collision analysis.Through these analyses,dimensions,structure weight and gravity center of the mooring system can be determined,which has some reference value for the design of soft yoke mooring system.
