A physical performance test device for forced roll stabilizer fins

Abstract

The invention discloses a forced roll stabilizer fin physical performance test device, which belongs to the field of ship engineering and includes a servo motor (1), a guide rail block (2), a swing transmission mechanism (3), a bearing, a shaft coupling, and a flange Disc, hollow cylinder (15) and torque sensor (9) and other parts. The movement of the fin stabilizer in a forced roll state is realized by means of a swing transmission mechanism (3) and a servo motor (1), and the moment generated by the fin stabilizer is measured by a torque sensor (9). By changing the rotational speed of the servo motor (1) and the length of the guide rail block (2), the physical performance test experiment of the forced roll stabilizer fin with different swing speeds and swing amplitudes can be carried out. The invention has a simple structure, is easy to process and manufacture, and has low cost, and is suitable for testing the physical performance of the forced roll stabilizer fins in various pools or tanks, and can also be used for measuring the physical performance of structures such as bilge keels.

Description

technical field [0001] The invention belongs to the field of ship engineering, in particular to a device for testing the physical performance of a forced roll stabilizer fin. Background technique [0002] When a ship is navigating at sea, due to the disturbance of the marine environment such as waves, sea wind and currents, it is inevitable to produce six degrees of freedom motion, namely rolling, pitching, yaw, sway, heave and surge. Because the damping of the ship's rolling motion is very small, the ship will produce violent rolling motion in wind and waves. Excessive rolling motion not only affects the navigation of the ship, but also has a negative impact on the equipment on the ship, and brings unsafe factors to the cargo and personnel on board. Therefore, ship designers and control engineers have been devoting themselves to developing effective anti-rolling devices to reduce the ship's rolling motion and improve the ship's seakeeping performance. Fin stabilizer is cu...

Problems solved by technology

However, the current model tests on fin stabilizers are basically installed on the ship model, and the anti-roll performance test of the fin stabilizer needs to be performed after the ship model rolls in the wave pool, resulting in high experimental costs
