The lift pipe subsystem of poly-metallic nodule mining system consists of steel pipe, pump, buffer, and flexible hose, whose kinematics and dynamics performances in water are crucial factors for the achievement of the deep sea mining. 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,其水下运动学和动力学行为,决定了深海采矿的成败。
Based on the mechanics model, the dynamic numerical simulations of launching of the long pipe line in deep-sea mining were carried out. The dynamics responses of the lift pipe system under the different launching operation modes were obtained, especially the initial configuration of the flexible hose. 基于该模型,进行了长管线系统布放过程的动力学数值模拟,得出了在不同布放操作模式下扬矿子系统的各种动态响应,尤其是软管初始构形的动态形成过程;
In order to find out the possible factors in effecting the performance of the mining vehicle, the hose force, advance thrusters, and the trim angle of the vehicle are analyzed by simulating. 并针对影响浮游式采矿车性能的可能因素,仿真分析了软管作用力、前进推进器推进力、采矿车纵倾角等因素对采矿车性能的影响。
Firstly, the main factor in effecting the performance of the mining vehicle is the hose force, advance thrusters, and the trim angle. 影响此浮游式采矿车性能的主要因素是软管作用力、前进推进器推进力、采矿车纵倾角和切削头作用力。
During the deep ocean mining process, it should make the hose in proper spatial configuration and ensure the hose meet the strength requirements. 在深海采矿扬矿过程中,既要保证软管具有良好的构形,又要能保证软管的强度要求。
