Description

TECHNICAL FIELD

[0001] The utility model relates to deep sea engineering technical field, concretely relates to a kind of test equipment of reproducible deep sea wind and wave environment. BACKGROUND

[0002] Offshore wind turbine and ocean platform and other marine engineering structures are important engineering equipment for marine resource development, which faces the complex coupling effect of wind, wave, current and other environmental loads during operation, which has important influence on the safety and stability of the structure. Therefore, before the construction of marine engineering structures, the dynamic response under various loads must be determined to ensure the rationality of design and the safety of operation. At present, the research on marine engineering structures mainly relies on physical model experiment, which can provide intuitive and reliable data support.

[0003] When carrying out physical model experiment, it is urgent to simulate the effect of wind, wave, current and other environmental loads on the structure at the same time to improve the accuracy and reliability of simulation results. At present, physical model experiment in the field of marine engineering is mainly carried out in experimental pool or water tank. For the simulation of wind load, a common way is to equivalent the effect of wind as constant load (i.e. direct force), which is simple and easy to implement, but cannot accurately reflect the dynamic characteristics of actual wind field. Another way is to use axial flow fan array to face the model, which can produce certain wind field effect, but still has certain limitations, especially cannot simulate atmospheric boundary layer wind profile, resulting in deviation between experimental results and actual working conditions.

[0004] Wave load simulation is generated by wave maker in pool or water tank. However, traditional water tank wave maker can usually only generate unidirectional regular or irregular waves, and cannot completely simulate multidirectional irregular waves in real marine environment. In addition, the coupling effect between wind, wave and current is extremely complex in actual marine environment, and existing experimental equipment and methods still face great challenges in simulating these coupling effects.
