| Abstract: | Deflective displacement of a mining pipe under the dragging force of the vessel and the combining effects of winds, waves, and currents were discussed. Mathematical modules of deflective displacement of a ladder pipe with pumps and buffer were built, and the equations were solved by Galerkin method. Simulated by computer, the characteristics of dynamic responses of a mining pipe under various conditions were analyzed. |
