| 摘 要： | 深海多金属结核开采系统的扬矿系统主要由扬矿硬管、扬矿泵、中间仓、扬矿软管等组成的长管线系统构成,其水下的运动学行为,决定了深海采矿的成败.运用几何非线性有限元理论对6000m深海采矿系统的扬矿系统进行了力学分析;在扬矿系统受管道及管内流体重力,海水浮力以及水平液动力作用的情况下,用有限元方法分别对几种工况下的扬矿系统进行了仿真计算,其结果可作为扬矿系统的设计和操作控制的依据.

| Abstract: | The lifting pipe subsystem of poly-metallic module mining system consists of steel pipe,pump,buffer and flexible hose,whose kinematic performances in water are crucial factors for the achievement of deep sea mining.Based on nonlinear finite element model,static numerical simulations of the force of the whole lift pipe system in 6000m deep-sea mining system are performed.Based on the fact that the transporting pipe is subject to the gravity of the pipe and the inner-pipe flow,the buoyancy and hydrodynamic fo... |
