Polymetallic Nodules In The Test Mining System Dynamics Simulation And Test Systems

With the decrease of mineral resources on land, the general trend is exploiting them on international deep sea bed. According to the plan of exploiting the mineral on international deep sea bed, China will make trial of ocean poly-metallic nodule pilot mining in 1000m deep in the eleventh five-year plan of Chinese government. Because of the particularity of abyssal environment and the complexity of the mining system itself, our country carries out the virtual reality research for the poly-metallic nodule mining system. It will shorten the research period and lower exploitation risk. It is necessary to develop a set of high-powered kinetic characteristic simulation and measurement system for the deep-sea mining system to provide similar movements and mechanical idiocratic reflection, analyze and study mechanical data and asway angle of each pivotal parts, provide reliable experimental validation platform and technical base for the selection of effective scheme. The major contents of this dissertation are as following:1. Simulative abyssal environmental forces of the simulation and kinetic measurement experimental system were analyzed according to action rule of the oceanic forces.2. Simulative experimental scheme with similar movements and mechanical idiocratic reflection of the mining system were confirmed after analyzing the movement rule of the main task process.3. A set of task simulation and kinetic measurement experimental system were built according to experimental scheme by use of mechatronics. Hardware and software of the system were designed .4. The data post-disposal platform were designed and some data were disposed by eliminating oddity items and smooth filter.5. Simulation experiment of the rigid pipe suffered from oceanic forces and buffer station were done. Experimental result were contrasted to the academic calculated value.
