根据海洋潜标测量系统实测的数据,包括海流流速、潜标深度等,拟合了一种接近于实际的海流剖面分布曲线,并基于有限元的方法编制了Matlab程序,数值计算潜标系统在海流作用下的偏降。并与潜标实际所处深度的几组代表性的数据进行了对比,计算结果与潜标实际布放产生的偏降数据吻合较好。并在此基础上分析了影响偏降的几个重要因素,对海洋锚泊测量系统偏降预估以及总体设计具有重要的工程参考价值。
According to the data measured by the oceanic subsurface measurement system, including the flow velocity of the ocean current and the depth of the submarine, a near-actual distribution curve of the ocean current is fitted and the Matlab program is compiled based on the finite element method. Off-shore under the current effect. And compared with several sets of representative data of the actual submerged depth. The calculated results are in good agreement with the partial drop data produced by actual laying of submarine. On this basis, several important factors that influence the partial drop are analyzed, which has important engineering reference value for the prediction of partial drop and overall design of marine mooring measurement system.
