摘要

目的分析矿物输送硬管在复杂海洋环境下动力学特性以及各参数的影响。方法基于Orcaflex软件,建立矿物输送硬管动力学仿真模型,计算不同工况下硬管的有效张力、等效应力结果,并分析浪向角、悬挂刚度、输送软管等敏感性参数对计算结果的影响。结果通过3个工况的计算,布放工况下硬管的最大有效张力和等效应力均远大于另外2个工况。通过参数敏感性分析,90°浪向角下最大有效张力和等效应力均出现了峰值,柔性软管会影响布放工况的计算结果,悬挂刚度会显著影响硬管的最大有效张力值。结论布放工况是硬管单根优化设计的关键工况。计算分析时,布放工况需考虑悬挂软管造成的影响,此外采矿船应顶浪布放,规避90°浪向角。硬管顶部悬挂刚度会很大程度上影响硬管随采矿船在海洋环境下的轴向运动,需充分计算后进行合理设置。

Abstract

The work aims to analyze the dynamic characteristics of a mineral conveying rigid pipe in complex marine environments and the effects of various parameters. A dynamic simulation model of the mineral conveying rigid pipe was established based on OrcaFlex. The effective tension and equivalent stress of the rigid pipe under different load cases were calculated, and the effects of sensitivity parameters such as wave heading angle, suspension stiffness, and the conveying flexible hose on the calculation results were analyzed. Based on the calculations of the three load cases, the maximum effective tension and equivalent stress of the rigid pipe under the deployment condition were far greater than those under the other two conditions. The parametric sensitivity analysis showed that the maximum effective tension and equivalent stress both reached their peak values at a wave heading angle of 90°, the flexible hose affected the calculation results of the deployment condition, and the suspension stiffness significantly affected the maximum effective tension of the rigid pipe. The results indicate that the deployment condition is the key condition for the single-pipe optimization design of the rigid pipe. In the calculation and analysis, the effect of the suspension hose should be considered under the deployment condition. In addition, the mining vessel should deploy the pipe in head seas to avoid the 90° wave heading angle. The suspension stiffness at the top of the rigid pipe greatly affects its axial motion following the mining vessel in the marine environment. Therefore, it should be reasonably set after sufficient calculation.
