单点系留式垂直剖面测量系统水动力仿真

Hydrodynamic Simulation of the Single Moored Vertical Profile Measuring System

单点系留式垂直剖面测量系统通过放置在主潜标上的绞车来控制升降平台上下运动,从而实现剖面的测量和数据传输。为辅助系统设计,文中介绍了通过OrcaFlex软件对该系统的水动力建模与仿真,并算出给定海况下几个重要部件的位置姿态和受力情况。结果表明:根据各节点拉力计算结果,选用合适的结构来满足各工况下的强度要求;仓体耐压和其它性能应满足主潜标最大下潜深度;升降的系缆所缠长度应满足平台运动过程释放的最大值。在实际配置系统时可以参考这几个重要数据辅助设计。

The single moored vertical profile measuring system controls the platform to move up and down through the winch placed on the submersible buoy, so as to achieve vertical profile measurement and data transmission to the satellite. In order to assist the design of the system, this paper focuses on the hydrodynamic modeling and simulation through the Orca Flex software, and derives some important results under given sea conditions. The results show that optimal structure should be designed to meet the strength requirement under various working conditions, the major submersible buoy will occur depth variation during complete work time, the cabin should be pressure-resistant to meet maximum diving depth, and the length of the lifting cable should suitable for the maximum length released during the motion process. All these important data can assist the design of whole system＇s structure.
