Mathematical model of a flexible pipeline for lifting minerals from the seabed surface

Article preview

A mathematical model is presented describing the configuration of flexible pipeline routes for a hydraulic mining complex for lifting ferromanganese and other nodules, as well as polymetallic sands, silt and crushed crustal formations from the surface of the seabed. The pipeline connects the subsea mining machine with the slurry receiver on the base vessel. The proposed model is based on the chain-link equation and describes the configuration of flexible, articulated pipeline routes over a wide range of distances between the base vessel and the mining machine. For the first time possible variants of chain line defining marginal boundaries of flexible pipeline location with positive buoyancy are constructed by analytical solution according to coordinate values. On the basis of the obtained results the peculiarities of mechanics of behavior of positive buoyancy flexible pipeline under its own load have been determined.

Calculation on the computer by the finite element method of stresses in the massif during cutting

Article preview

The nature of rock fracture under the action of the cutter depends on the stresses in the area of their concentration in the massif, determined by its outlines and the applied force. In the process of cutting the boundaries of the array, the magnitude and angle of the applied force with the contact site change.

Расчет входных углов в элементах гидродинамической схемы двухступенчатой активной гидротурбины

Article preview

Экспериментальные и теоретические исследования, проводимые в ЛГИ по созданию двухступенчатой активной гидротурбины с наклон­ноструйными ступенями, гидродинамическая схема которой представ­лена на рисунке, показали, что характеристики таких турбин вполне отвечают задачам турбопривода на гидрошахтах и имеют ряд преиму­ществ. Из них наиболее важны сравнительно низкая удельная быстро­ходность двухступенчатого турбодвигателя, малый радиальный размер и характерный для двигателя осевой отвод отработавшей воды. Как показали испытания экспериментального образца такого турбодвигате­ля, при правильном задании конструктивных параметров, по своему к. п. д. он может не уступать применяемым в настоящее время радиаль­ным и ковшовым турбодвигателям ...
