摘要
根据软管采矿系统工作时管道的运动规律 ,采用合适的海流速度的经验计算公式和微幅重力波理论 ,推导出了输送管道运动时海水质点与管道的相对速度和加速度的计算公式 ;然后根据Morsion方程 ,推导出在海浪和海水作用下的管道运动的阻力计算公式。上述管道运动的阻力计算公式可直接应用于采矿系统的载荷分析。
Based on the law of motion for transporting pipes in hose mining system, calculation formulas have been derived, by adopting proper empirical formular for ocean current and gravity wave theory, for relative velocity between seawater and pipes and its acceleration while transporting pipes moving. The calculation formulas for the resistance to motion of pipes under the effect of sea wave and seawater have been deduced based on the Morsion equation. Such calculation formula for resistance to motion also can be directly applied into the load analysis for mining system.
