Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] In practice, the wave-making principle of the circular-orbit oscillating horizontal cylinder deep-water ice test pool is as follows: first, assume that the radius of the horizontal cylinder is a, and the horizontal cylinder performs periodic simple harmonic oscillation motion with frequency ω; in order to describe the fluid motion and ice For layer bending deformation, two coordinate systems are selected, namely the Cartesian rectangular coordinate system O-xz, and the polar coordinate system o-rθ fixed on the cylinder. The formula x=rsinθ+η can be used between the two coordinate systems 1 cosα 1 , z=rcosθ-(h-η 3 cosα 3 ) and α j =ωt+γ j mutual conversion; among th...

Abstract

The invention discloses a wave generation and combined water-absorbing system for deep-water ice test tank with horizontal cylinder in circular-track oscillation. The system comprises a wave generation mechanism, a first wave-absorbing mechanism, a second wave-absorbing mechanism, a first longitudinal frame, a second longitudinal frame, an infrared sensor, a simulated ice layer and a test tank body; the wave generation mechanism is arranged between the first wave-absorbing mechanism and the second wave-absorbing mechanism and close to the first wave-absorbing mechanism; the wave generation mechanism is used for producing bending gravity wave in one-way propagation; the first wave-absorbing mechanism and the second wave-absorbing mechanism are used for evading the reflection of the bendinggravity wave on a sidewall of the test tank body; the simulated ice layer is arranged at an opened end of the test tank body; the first longitudinal frame is arranged above the wave generation mechanism, and the second longitudinal frame is arranged at the inner wall of one side corresponding to an opening of the test tank body; the infrared sensor is arranged above the simulated ice layer and used for monitoring a bending deformation condition of the simulated ice layer. The system disclosed by the invention can precisely produce the one-way advancing bending gravity wave of the ice tank, andcan effectively adjust a waveform parameter.

Description

technical field [0001] The invention belongs to the technical field of deep-water ice test pool equipment manufacturing, and in particular relates to a wave-making and combined wave-suppression system for a circular-rail oscillating horizontal cylinder deep-water ice test pool. Background technique [0002] As the thickness and coverage of sea ice in the Arctic continue to shrink, the Arctic shipping lanes are gradually opened. The Arctic waterway is the shortest route connecting the three continents of Asia, Europe and the United States. Compared with the traditional Suez Canal and Panama Canal routes, using the Arctic waterway can shorten the voyage by thousands of kilometers. Therefore, the opening of the Arctic waterway will greatly reduce commercial transportation costs. Including Russia, North America, Europe, and East Asia's Circum-Arctic Economic Circle. At the same time, large-scale development of Arctic resources has become a reality. According to estimates, the ...
