深海采矿是我国“海洋强国”战略的一个发展方向,也是保障国家资源安全的重要举措。以郭小刚教授领衔的“深海采矿系统可靠性”研究团队,以理论分析、编程计算、数值仿真和试验研究为手段,长期从事复杂海洋环境下深海采矿系统的可靠性研究。团队主要由郭小刚教授、邓旭辉副教授、马雯波副教授、涂佳黄副教授、唐现琼博士、宋奎博士、刘秀博士等组成。

团队研究内容包括但不局限于:风浪流对采矿船的动力激励、洋流对水下管线的空间构形和动力学行为的影响、水下管线的涡激振动效应、海底稀软底质土力学特性、集矿机在海底的行走特性、深海采矿系统的动力学行为、系统作业过程的安全性和稳定性、管线空间设计、采矿作业路径规划、新型深海采矿方法与技术等。

近三年,团队密切参与1项国家自然科学基金重点项目、1项大洋协会十二五重大课题和1项大洋协会十三五海上试验课题,主持2项国家自然科学基金青年基金项目,1项湖南省重点研发计划项目及多项其它省部级课题。发表相关论文20余篇,申报专利和软件著作权7项,研发新型试验装置3套。取得的关键成果包括:(1)基于空间非线性梁理论的软管动力学计算理论、方法和软件;(2)单参数任意挠度非线性悬链线理论、计算方法和软件;(3)水下柔性管线空间构形设计及其动力学分析方法;(4)深海采矿系统联动作业理论、方法和技术等。团队认真参与了省政协组织的“加快我省深海采矿资源开发技术与装备产业”的调研和座谈会,积极建言献策,推动深海采矿事业的发展。团队部分研究成果被应用于大洋协会十二五课题的浅海(70米)试验(20185月,东海)和十三五课题的500米海上试验(20186月,南海),这2次试验均是我国首次在不同深度进行的采矿验证试验,均取得了圆满成功;团队的研究成果经受了实践的检验,受到主持单位的好评。

Introduction to the Research Teamof “the Deep-Sea Mining System”

The “deep-sea mining”plays anessentialrole in implementing maritime power strategy and ensuring the security of state resources.The team has researched on “the reliability of the deep-sea mining system” for many years, by means of theoretical analysis, programming calculation, numerical simulation and experiments. Major researchers include Professor Guo Xiaogang, associate professor Deng Xuhui, associate professor Ma Wenbo, associate professor Su Jiahuag, Dr.Tang Xianqiong, Dr. Song Kui, Dr. Liu Xiu and so on.

The research team focuses on the dynamic excitement of wind flow on mining vessel, the influence of ocean current on the spatial configuration and dynamic behavior of the sub-water pipelines, vortex-induced vibration of the subwater pipelines, Mechanical properties of deep-sea sediment, the sub-watermoving characteristic of ocean mining machine, the dynamic behavior of the deep-sea mining system, the security and stability of the operation process, spatial design of the pipelines, the route planning of the mining operation, the new method and techniques of the deep-sea mining, etc.

For the last three years, the research team has participated one key research project supported byNatural Science Fund, one key project of the Twelfth Five-Year Plan and one sea test project of the 13th Five-Year Plan supported by COMRA. In the meantime, the team has hosted two National Youth Science Fund Projects, one key research and development planned project of Hunan Province and many other provincial projects. The team has also published more than 20 researched paper, obtained 7 patents and software copyrights, and developed 3 new-style experiment equipment.

The research achievements are as follows: thedynamic calculation theory, method and software of the soft pipes based the Spatial nonlinear beam theory;thetheory, method and software of single-parameter nonlinear catenary with arbitrary deflection;the spatial configuration design and the dynamic analyticalmethod of the underwater flexible pipelines;the linkage operationtheory, method and software of the deep-sea mining system.

The research team has participated in the survey and seminars of “accelerating the development technology and equipment of deep-sea mining” organized by Hunna Provincial Political Consultative Conference. A part of research results has been used in the 70 meter-deep sea experiment of the 12th Five-Year Plan project supported by COMRAand the 500-meter-deep sea experiment of the 13th Five-Year Plan project supported by COMRA. These two mining experiments, one in the East Sea in May and the other in the South Sea, both succeeded and validated the research results.
