Abstract

The invention relates to the technical field of three-dimensional simulation of flexible pipelines, in particular to a flexible pipeline test system and a three-dimensional numerical simulation method based on complex marine environments. The flexible pipeline test system includes a model input module, a numerical simulation module, and a physical model test system. module, an experience learning library module and a host computer. The experience learning library module includes a practical example library module and a previous calculation example library module. The practical example library module inputs the existing use and actual measurement data of the submarine flexible pipeline in the past. This application combines the numerical calculation simulation method and the physical model test method, and uses the two methods to cross-validate each other, so that the numerical calculation and the physical test model can obtain as accurate results as possible. At the same time, this application excludes the numerical calculation due to input Numerical calculation errors caused by inaccurate initial parameters can also prevent errors in physical model experiments due to size effects; at the same time, use neural network learning to speed up the convergence speed and efficiency of numerical calculations.

Description

technical field [0001] The invention relates to the technical field of marine pipelines, in particular to a test system for flexible pipelines based on complex marine environments. Background technique [0002] In recent decades, countries around the world have maintained sufficient vigilance against the contradiction between the almost unlimited energy demand and the limited fossil resource reserves. Especially since the outbreak of multiple oil crises since the 1970s, it has triggered long-term structural changes in the world's energy market. The world's major oil-importing countries have begun to actively seek alternative energy sources and develop energy-saving technologies. However, since the research and development and marketing of energy-saving products often require a lot of time and capital investment, and the alternative energy with sufficient quantity and stable supply is still in a long process of exploration, the current situation of over-reliance on fossil ene...
