【摘要】 根据深海采矿输送管道在采矿船牵引下运动,同时受到管道和管内流体重力、浮力和海水阻力作用的情况,采用有限元对输送软管进行了计算分析.从计算结果的比较分析可知:在输送管道下端安装浮体,得到了一种十分理想的采矿系统;海流和海浪对管道上端的结点反力有较大的影响,对管道下端的结点反力和管道的形状影响较小;采矿船运动对管道产生很大的阻力,对管道两端的结点反力和管道形状影响都很大.图8,表1,参9.更多还原

【Abstract】 Based on the fact that the transporting pipe is atlected under the interaction of the draft of mining vehicle and ship,the gravity of the transporting pipe and the inner liquid,the buoyancy as well as the hydrodynamic forces,the transporting systems were analysed.Conclusion show that the ideal mining transporting system is obtained by installing buoy along the under part of the transporting pipe.The current and ocean wave exert large influence on the upper-end forces of the transporting pipe while small influence is exerted on the bottom-end and transporting pipe shape.The great hydrodynamic forces on transporting pipe cause by the mining ship movement influence the forces on both ends of transporting pipe and the transporting pipe shape greatly.8figs.,1tab.,9refs.更多还原
