Experimental device for water entry and wave-making movement of multi-angle objects

Abstract

The invention provides a multi-angle object water entry and wave-making experimental device, which is a new type of water entry experiment device with diversified water entry methods, controllable water entry angle and water entry speed, and is suitable for the water surface and underwater of the model at different immersion depths. Wave experiment. The present invention is composed of experimental water tank, drive system, power cabinet, control system and high-speed photography system; drive system is composed of support frame, horizontal test platform, vertical test frame and angle connector; angle connector connects horizontal test platform and vertical test frame , to realize the linkage between the horizontal movement and the vertical movement of the system, and adjust the angle of the structure entering the water. By separately controlling the speed values ​​of the horizontal test bench and the vertical test frame, the oblique water entry, variable speed water entry and wave-making experiments can be realized. The invention has the characteristics of diverse experimental means, high result accuracy, high device utilization rate, high equipment adaptability and the like.

Description

technical field [0001] The invention relates to an experimental device in the field of ship and ocean engineering experiments, in particular to an experimental device for multi-angle objects entering water and wave-making motion, which is mainly used in the research of water-entry experiments of structures and wave-making motion experiments. Background technique [0002] In recent years, China has proposed national future development strategies such as "One Belt, One Road" and "21st Century Maritime Silk Road", and the fields of ships and ocean engineering have received great attention. The problems of structure entry into water and wave-making motion are research hotspots in the field of shipbuilding and ocean engineering. The problem of water entry of structures has important engineering value in aspects such as slamming into water of offshore platforms and ships, take-off and landing of seaplanes at sea, and entry of missiles and torpedoes into water. The water entry of ...

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
