Description

technical field [0001] The invention belongs to the technical field of offshore platform test devices, and relates to a hybrid model test platform for deep-sea platform vibration control. Background technique [0002] With the increasing demand for global oil and gas resources and the gradual depletion of onshore oil and gas resources, the development of offshore oil and gas resources has attracted more and more attention from various countries, and exploration and development have increasingly extended to the deep sea. As the basic facilities for the development of deep-sea oil and gas resources, the number of deep-sea platforms is increasing. At present, the key technologies of deep-sea platforms are mainly mastered by European and American countries, and my country's research on deep-sea platform technology is in its infancy or even has not yet set foot in it. It is certain that my country will inevitably develop into the deep sea, and the research results of model tests...

AI Technical Summary

Problems solved by technology

[0004] 1. Relevant research at home and abroad is more focused on the vibration control research of offshore fixed platforms, and the theoretical calculation and experimental research on deep-sea platform vibration control technology is less involved, and the engineering application of deep-sea platform vibration control is even less. few

[0005] 2. Scholars at home and abroad mainly use shaking table experiments to study the vibration reduction effect of structural vibration control devices, but there is still a lack of directly related results or experience obtained through tank experiments and pool experiments

Moreover, currently there are few special pools capable of simulating the marine environment, and the deep-sea platform model test is limited by the scale of the laboratory and test equipment, and the test cost is very expensive, making it difficult to conduct multiple tests

[0006] 3. Numerical tank tests are widely used in ship type performance design and have played an important role in ship type optimization and innovative design. However, numerical tank test methods are rarely used in the R&D and design of offshore platforms. Numerical tank tests and physical tests are combined Combined research has not yet been reported in the literature
