Experiment device for stable multi-angle entering-into-water of object

Abstract

The invention belongs to hydraulic experiment model facilities, and particularly relates to an experiment device for stable multi-angle entering-into-water of an object. The experiment device comprises a transparent water tank, an electromagnetic releasing device and a data acquisition system. The electromagnetic releasing device comprises supporting columns and a vertical rod. One end of the vertical rod is hinged with a transverse supporting rod through a first hinge joint, and the other end is hinged with an electromagnet block through a second hinge joint, wherein a water entering object is attracted with the bottom of the electromagnet block. A transverse water entering angle adjusting pointer and a longitudinal water entering angle adjusting pointer are vertically fixed on different sides of the vertical rod. A transverse water entering angle protractor is fixedly arranged on the transverse supporting rod. A longitudinal water entering angle protractor is fixedly arranged on the electromagnet block. The electromagnetic releasing device is connected with an industrial control computer through a cable. The data acquisition system comprises a synchronization instrument, a laser transmitter, a high-speed image photographing instrument and a high-speed camera, wherein the synchronization instrument is controlled by the industrial control computer. The experiment device can stably release water entering objects with different shapes and furthermore can accurately control the water entering angles of the objects.

Description

technical field

[0001] The invention belongs to hydraulic experiment model facilities, in particular to a multi-angle water entry experiment device for stabilizing objects. Background technique

[0002] The problem of objects entering and exiting water widely exists in many fields such as military affairs, engineering, and daily life, such as submarine-launched missiles, anti-submarine missiles, high-speed torpedoes, return cabins entering water, submarines entering water, aircraft forced landings on water surfaces, athletes diving, etc. In terms of theoretical research and practical applications Both have important value and have always been a very important research topic in the field of shipbuilding and ocean engineering. Although the process of entering and exiting water is only a very short transient process, this short process has obvious characteristics, involving strong nonlinear free surface motion and breaking, turbulence and vortex, motion and deformation of objec...
