摘要
深水连接器作为水下生产系统的关键组成部分,潜水员无法辅助其完成安装过程,其自身对中性能的好坏至关重要。针对应用于1 500 m水深的?304.8 mm水平套筒式连接器毂座止口对中结构,将其进行参数化后,得到了其在不同对中形式下仍能满足要求时的参数约束条件,并研究分析了各参数与对中性能的影响关系。最后在角度偏离的工况下,考虑最大纠偏能力大于10°等约束条件,得到了相应的半无限多变量约束条件,以止口结构的最大纠偏量为优化目标,采用Matlab优化工具箱的fseminf函数优化出各参数的最佳取值。所得结果为深水套筒式连接器止口结构的优化设计提供了理论基础。
Deepwater connector is a key part of subsea production system?Its installation can not rely on di?vers, so its alignment performance is crucial?For hub seat mouth alignment structure of ?304?8 mm horizontal sleeve type connector used for water depth of 1 500 m, it is parameterized to obtain parameter constraints under which the structure can meet requirements for different alignment forms?Moreover, the relation between parameters and alignment performance is analyzed?Finally, semi?infinite multi?variable constraints are obtained based on maxi?mum deflection rectifying ability above 10° and other constraints under the condition of angle deviation?Maximum deflection rectifying amount of mouth structure is taken as the optimization objective and fseminf function of Matlab optimization toolbox is used to optimize the best value of parameters?The results provide a theoretical basis for opti?mal design of deepwater sleeve type connector mouth structure.
