[0002] The vast sea area and complex and changeable sea conditions have created a complex and changeable marine environment. In recent years, with the continuous deepening of marine scientific research and marine resource development, the diverse meteorological conditions have put forward higher requirements on the safety performance and working efficiency of various marine equipment. Especially under severe climatic conditions, marine experimental instruments and equipment need to have stronger wind and wave resistance to ensure their reliability and stability in complex marine environments.

[0003] Since marine experiments and testing tasks often need to be carried out under extreme marine conditions such as wind and waves, or even in severe weather conditions such as typhoons and storm surges, the drastic changes in sea surface wind and waves pose a great challenge to the stability, reliability and safety of marine facilities and equipment, and put forward more urgent demands on the ability of experimental equipment to resist wind and wave impact. However, most traditional marine testing devices lack special designs for wind and wave impacts, and are prone to displacement, tilt, flipping or damage when encountering extreme sea conditions such as strong winds and huge waves, which seriously affects the accuracy of experimental data and the smooth progress of tasks.

[0004] Currently, there is an urgent need to develop an experimental test device and an experimental test method for resisting wind and wave impact. Summary of the invention
