中文摘要：
以移动式海上基地（MOB）作为研究对象,提出其柔性连接构件在恶劣海况下的动约束力简化计算方法,并采用该方法计算、分析了MOB连接构件动约束力随不同参数的变化规律。该算法采用修正后的Morison方程替代势流理论计算MOB所受波浪力,对目前常用的计算方法进行了简化。将该算法与基于势流理论算法的计算结果进行对比,验证了该算法的正确性与合理性。采用该算法计算了不同海况等级、波浪入射方向、连接构件刚度条件下的MOB柔性连接构件动约束力,结果表明：在x方向上动约束力随浪向角的增加而减小,在y、z方向上动约束力随浪向角的增加先增加后减小;海况等级越高连接构件动约束力越大;随着连接构件刚度的增加动约束力近乎线性递增;相同条件下不同连接构件受力较均匀。
英文摘要：
Mobile offshore base（MOB） was treated as a research object, and a simplified algorithm was developed for determining the dynamic constraint forces on flexible connectors of MOB at rough sea states. The algorithm was adopted to calculate and analyze the fluctuation laws between dynamic constraint forces and different parameters. The wave loads on MOB structures were evaluated based on the revised Morison equation instead of potential flow theory, and the conventional computational methods were simplified. The numerical results of the simplified algorithm were compared to those of the algorithm based on potential flow theory for validating the correctness and reasonability of the simplified algorithm. The simplified algorithm was used to estimate the dynamic constraint forces on flexible connectors of MOB under different sea states, wave incident directions, and connector stiffness values. The results show as the wave angle increases, the dynamic constraint force decreases in the x direction, while increases first and then decreases in the y and z directions; the dynamic constraint force increases as the sea state increases, and shows a trend of linear increasing with the connector stiffness increasing; the dynamic forces on different connectors are well even in the same conditions.
