1000m deep-sea mining system of three-dimensional dynamic analysis of the overall linkage

000m deep water, the mechanical test system based on the analysis, finite element analysis software ANSYS7.0 as the computing platform, the system is equivalent to the different properties of each part of the beam pipe, the establishment of a long pipeline system, nonlinear finite element model, Water liquid pipelines under dynamic loading using Morison formula. (2) calculated at the rate of straight-line towing conditions the lateral offset of the middle positions. In order to maintain the hose in the water space saddle shape, mining machine and the distance between positions appropriate to maintain the 120 ~ 160nl, so mining machine should be less than 0.5m / s speeds. * 2 quality,Ed Hardy mexico, 2002,14 (4): 251 ~ 2545 Wei Xin Chao, Han Yue new.

Changsha: Central South University, 2001 (Received 20o4 a l2-2O) (3) of the 3 typical patterns of the overall linkage towing path computer simulation results show that: the 0.5m / s of the towing speed, Drag the middle position of the trajectory and the trajectory of the ship is consistent with good system to follow. (4) The effects of lifting system in the process of towing a variety of dynamic mechanical properties. The results showed that: the top tube lifting the level of force in the mining ship large changes in the process of turning movement, and lifting the top of the vertical tube the dynamic tensile strength was steady alternating force; the overall interaction process, Yang Mine smaller tube bending stress, axial stress greatly, the maximum dynamic axial stress is 131MPa, much less than the tensile strength of tube material.
