團隊負責人郭小剛教授(深海采礦研討會,2017)
深海采礦是我國“海洋強國”戰略的一個發展方向,也是保障國家資源安全的重要舉措。以郭小剛教授領銜的“深海采礦系統可靠性”研究團隊,以理論分析、編程計算、數值仿真和試驗研究為手段,長期從事復雜海洋環境下深海采礦系統的可靠性研究。團隊主要由郭小剛教授、鄧旭輝副教授、馬雯波副教授、涂佳黃副教授、唐現瓊博士、宋奎博士、劉秀博士等組成。
團隊研究內容包括但不局限于:風浪流對采礦船的動力激勵、洋流對水下管線的空間構形和動力學行為的影響、水下管線的渦激振動效應、海底稀軟底質土力學特性、集礦機在海底的行走特性、深海采礦系統的動力學行為、系統作業過程的安全性和穩定性、管線空間設計、采礦作業路徑規劃、新型深海采礦方法與技術等。
近三年,團隊密切參與1項國家自然科學基金重點項目、1項大洋協會十二五重大課題和1項大洋協會十三五海上試驗課題,主持2項國家自然科學基金青年基金項目,1項湖南省重點研發計劃項目及多項其它省部級課題。發表相關論文20余篇,申報專利和軟件著作權7項,研發新型試驗裝置3套。取得的關鍵成果包括:(1)基于空間非線性梁理論的軟管動力學計算理論、方法和軟件;(2)單參數任意撓度非線性懸鏈線理論、計算方法和軟件;(3)水下柔性管線空間構形設計及其動力學分析方法;(4)深海采礦系統聯動作業理論、方法和技術等。團隊認真參與了省政協組織的“加快我省深海采礦資源開發技術與裝備產業”的調研和座談會,積極建言獻策,推動深海采礦事業的發展。團隊部分研究成果被應用于大洋協會十二五課題的淺海(70米)試驗(2018年5月,東海)和十三五課題的500米海上試驗(2018年6月,南海),這2次試驗均是我國首次在不同深度進行的采礦驗證試驗,均取得了圓滿成功;團隊的研究成果經受了實踐的檢驗,受到主持單位的好評。

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: ①thedynamic calculation theory, method and software of the soft pipes based the Spatial nonlinear beam theory;②thetheory, method and software of single-parameter nonlinear catenary with arbitrary deflection;③the spatial configuration design and the dynamic analyticalmethod of the underwater flexible pipelines;④the 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.
