摘要
为研究铰接式扬矿系统的动态影响,分析了波浪液动力、流体阻力和流体附加质量对多段铰接式连接扬矿系统的影响,采用拉格朗日方程建立系统的运动数学模型,并对系统的运动响应进行数值模拟;计算结果和实验基本相符。当海浪周期较小时,中间舱在平衡位置作微幅运动,系统若处于这种海况时,有利于采矿作业。这一结果为我国采用铰接式连接扬矿系统进行1 000 m海上开采(试验)提供了理论依据。
To study the dynamic effect of articulated ocean mining lifting system, the wave hydrodynamic force, hydraulic resistance and added mass of fluid are analyzed. The motion mathematical model is established for the lifting system by using Lagrange equation and is used to numerically simulate the dynamic response of the lifting system. The simulation results are found basically similar to those of the test. When in short wave cycle, the middle bin of the lifting system will be in perturbation, which is beneficial for the mining system. The result has provided a theoretical basis for the application of 1000m seabed mining （test） using articulated mining lifting system in China.
