摘要
为了掌握和求解深海浮式结构的完整稳性计算原理及优化过程,指出常规船体与浮式结构物在稳性计算方面的主要区别,建立了浮式结构物浮态坐标系,给出适合于浮式结构物稳性计算的两类浮态参数,同时给出了两者间转换关系;推导出浮式结构空间稳性臂计算公式,并给出具体的推导过程及最终表达形式.在此基础上,引入最小消耗功的概念,给出了空间最小稳性臂的优化计算原理和方法.
This paper was aimed at grasping the intact stability calculational principle and optimization procedure of deepwater floating structures（FS）. The main differences on the stability calculation between the ship and FS were pointed out. The floating condition coordinate was set up and two kinds of parameters which were suited for stability calculation were offered. The transformation between the two kinds of parameters was also provided. The spacial stability arms expressions were deducted and the process and the results were also provided. The concept of minimal power was imported and the optimal calculational principle and method of spacial minimal stability arms was offered.
