Abstract

The invention relates to the technical field of flexible pipeline three-dimensional simulation, in particular to a flexible pipeline test system based on a complex marine environment and a three-dimensional numerical simulation method, and the flexible pipeline test system comprises a model input module, a numerical simulation module, a physical model test module, an experience learning library module and an upper computer, the experience learning library module comprises a practical instance library module and a previous calculation instance library module, and the practical instance librarymodule inputs the use and actual measurement data of the existing previous submarine flexible pipeline. According to the method, a numerical calculation simulation method and a physical model test method are combined, and the two methods are used for cross validation, so that the numerical calculation and physical model test results are as accurate as possible, meanwhile, numerical calculation errors caused by inaccurate input initial parameters of numerical calculation are eliminated, and the accuracy of numerical calculation results is improved. Errors of a physical model test caused by a size effect can be prevented; meanwhile, the convergence speed and efficiency of numerical calculation are increased through neural network learning.

Description

technical field [0001] The invention relates to the technical field of marine pipelines, in particular to a test system and numerical simulation method for flexible pipelines in complex marine environments. Background technique [0002] In recent decades, countries around the world have maintained sufficient vigilance against the contradiction between the nearly unlimited energy demand and the limited fossil resource reserves. In particular, the outbreak of oil crises since the 1970s has triggered long-term structural changes in the world energy market. Major oil-importing countries in the world 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 ...
