Auxiliary experimental device for water entry experiments of structures

Abstract

The invention provides an auxiliary experimental device for the water entry experiments of structures. The auxiliary experimental device comprises a launch pad and an impact water tank; the tilt angleof the launch pad can be adjusted within a range of 0 to 90 degrees, and the position of the launch pad can be also adjusted along a longitudinal direction; the problem of the oscillation of the launch pad under the impact of a reaction force is specially designed, so that the stability of the launch pad can be ensured; as a platform, the launch pad can be configured with different launch modulesto form a launch system; the wall surface of the impact water tank is made of a transparent material, and therefore, the impact water tank enables a good view-finding field of vision; the water tankis reinforced, and the deformation degree of the water tank at a depth of two meters of water is limited to a range in which the light of a camera is not significantly refracted; since the depth of the water tank is large, the water tank can be used for the high-speed water entry experiments of the structures.

Description

technical field [0001] The invention relates to the field of hydrodynamic experiments, in particular to an auxiliary experimental device in the field of water entry experiments of structures. Background technique [0002] The engineering application of structure water entry research is extremely extensive, and is closely related to industry, national defense, and even our life, from the landing and forced landing of seaplanes and passenger planes on the water surface, the wave slamming of ships and ocean structures, to the airdropping of torpedoes and depth bombs The entry into water, the launch of underwater weapons or aircraft, all reflect the practical application of research on water entry. [0003] The whole process of a structure entering water generally refers to the time course from when the head touches the water to when it is completely wet. In the process of entering the water, the structure will go through four stages: water collision, flow formation, cavitation...
