Dynamic analysis of the integrated motion operation mode of the total deep ocean mining system
摘要
Abstract
Taking the design scheme of China' s deep ocean mining pilot system as the engineering background, the 3-dimensional dynamic model of the total deep ocean mining system was established based on the single-rigid-body of the seafloor tracked miner, the multi-body discrete element model of the pipeline and the kinematics model of the surface mining ship. A new integrated motion operation mode was proposed, which combines of longitudinal straight-line motion, turning motion and lateral straight-line motion. The dynamic simulation analysis of the new operation mode was achieved. Some critical dynamic characteristics results during the whole operation process were obtained, such as the motion trajectories of the main subsystems, the interaction forces between adjacent subsystems, the deflection angles of the rigid lift pipeline and etc. The dynamic simulation results show that the motion states of all the subsystems can keep stable within the permissible ranges during the whole operation process, which further prove the rationality and feasibility of the newly proposed integrated motion operation mode.关键词
