Embodiment Construction

[0016] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] The invention relates to an experimental device for simulating the ice-breaking of an under-ice vehicle in different motion modes, and is mainly used for studying the ice-breaking ability of the vehicle under the ice surface in different motion modes. When the present invention is in use, the water surface in the pool is first frozen into an ice surface in a low-temperature laboratory, and the motion track drives the hydraulic lifter to move forward at a certain speed. The model sails under the ice in different motion modes, and the navigation body causes the surrounding fluid to be disturbed, and the disturbance is transmitted to the ice surface, which excites the ice surface to generate hydroelastic waves. The depth locator measures the submerged depth of the vehicle, and the vertical displacement sensor records the deformation characteri...

Abstract

The invention belongs to the technical field of ship icebreaking and particularly relates to an experimental device for simulating the icebreaking of an under-ice navigation body in different motion modes. According to the invention, the submergence depth of the navigation body is measured through depth locators installed at two sides of a pool, the hydraulic lifting instrument is utilized to drive an under-ice navigation body model to move below an ice surface in different motion modes, therefore, the ice surface is excited to generate water elastic deformation, a head portion and a tail portion of the navigation body model are driven by the hydraulic lifting instrument to move in a certain mode, so the motion trail of the model is controlled, the deformation of the ice surface is measured through a vertical displacement sensor on one side of the pool, the icebreaking condition of the ice surface is observed, and the research on the icebreaking capacity of the underwater navigation body in different motion modes is achieved. Model motion modes and navigation depths can be selected in a user-defined mode, meanwhile, the model shape and the ice layer thickness can be changed, and the damage degree of the ice surface under the action of different factors can be efficiently studied.

Description

technical field [0001] The invention belongs to the technical field of ship ice breaking, and in particular relates to an experimental device for simulating the ice breaking of an under-ice navigation body in different motion modes. Background technique [0002] In the polar regions, the existence of ice provides natural concealment conditions for submarines, but at the same time it also hinders the need for submarines to go out of the water to perform tasks. In order to allow submarines to successfully break the ice and get out of the water, the research on submarine ice-breaking technology has become the focus of national defense. The United States and Russia have already broken through the technology of using the submarine's own structure to float up and break the ice. However, this method of floating the submarine itself to break the ice has a relatively large requirement on the structural strength of the submarine, and higher requirements on the design of the submarine...
