Problems solved by technology

[0004] Due to the large water area of ​​the spiral arm pool, if simulated ice blocks are laid on the water surface within a certain range of water area, if it is not restricted by external blocking objects, the density of simulated ice blocks in the simulated ice area is difficult to reach the required value for the test. This will cause a large error in the test simulation environment, which will have a serious impact on the test results of the ship model ice-breaking slewing load

Abstract

The invention relates to a variable-diameter floating ice channel, including a pool, a central island is arranged in the center, a bracket is fixedly installed on the side wall of the central island, an arc-shaped inner channel is installed at the end of the bracket, and the inner channel and the central island are arranged concentrically; A trolley track is installed, a mobile trolley is installed on the trolley track, and the mobile trolley moves along the radial direction of the central island under the guidance of the trolley track; an arc-shaped outer channel is installed on the mobile trolley, and the outer channel and the inner channel are set concentrically. The outer channel is composed of multiple small channels arranged along the circumferential direction. The small channel in the middle is connected with the mobile trolley, and the adjacent small channels on both sides are connected by a rotating mechanism; the inner channel and the outer channel are connected by rotation. A floating ice channel is formed between them; the distance between the outer channel and the inner channel is changed under the driving of the moving trolley, and the outer channel is driven by the reducing mechanism to change the radius of curvature, so as to realize the radial dimension of the floating ice channel. The adjustment makes the pool test function diversified, greatly improves the pool test efficiency and saves the cost.

Description

technical field [0001] The invention relates to the technical field of ship model test equipment, in particular to a variable-diameter floating ice channel. Background technique [0002] The swivel arm pool is mainly used for the test and research of the maneuverability of the surface ship model rotation. The swing arm pool is usually a circular pool structure. A central island with a fixed rotary shaft is arranged in the center of the pool body. A circular track is laid on the periphery of the pool body. A rotating arm is set up between the rotary shaft and the circular track. Install a trailer that can change the radius along the radial direction, and the ship model is connected with the trailer through a force-measuring balance and a support rod. During the test, the rotating arm was moved at a certain rotation speed, and the ship model was forced to rotate with a certain radius of rotation by the trailer, and a series of hydrodynamic test parameters of the ship model we...
