Background technique [0002] In recent years, China has put forward national future development strategies such as "One Belt, One Belt" and "21st Century Maritime Silk Road", and the fields of shipbuilding and ocean engineering have received great attention. The problem of structural water entry and wave-making motion is a research hotspot in the field of ship and ocean engineering. The problem of water entry of structures has important engineering value in water slamming of ocean platforms and ships, seaplane takeoff and landing, and missile torpedo entry into water. According to the water inlet speed, the structure can be divided into high-sp...

AI Technical Summary

Problems solved by technology

[0005] (1) The adjustment of the water entry angle of the structure is not considered or the angle control method is too simple, resulting in errors in the measurement results, and it is difficult to guarantee the accuracy of the data, and the expected experimental results cannot be achieved;

[0006] (2) The implementation of water entry methods for structures is too simple, and it is impossible to comprehensively realize multiple water entry methods such as free entry into water, forced entry into water (uniform speed and variable speed), which increases the cost of experiments;

[0007] (3) The function of the experimental device is too single, only a single water entry experiment can be carried out, it is not applicable to other types of experiments, and the utilization rate of the experimental device is low
