| 摘 要： | The experiment system of 1000 m deep sea mining system is built up with the similarity theory.Sine mechanism is used to simulate mining ship to generate lateral shock excitation by ocean wave.Simulation and experiment of spherical joint connecting deep sea mining system has been done in band six marine conditions.The results indicate that the moment of spherical joint connecting deep sea mining is smaller than that of the thread connected ones,the lifting pipe of spherical joint is "flexible pipe".The flexural torque of the articulated lifting pipe system in pump and buffer is generally periodic variation with some irregularity,the value is stable on 60 N·S,and it is obviously smaller than that of the fixed lifting pipe system;The total displacement exhibits cyclic variation pattern,and the periodicity of them is longer than that of sea current.The results of experiment and simulation are basically consistent.And the analysis in the paper offers theoretical foundation of 1000 m deep sea mining system in China.
