Three-degree-of-freedom propeller test platform suitable for vertical circulating water tank and test method

Abstract

The invention discloses a three-degree-of-freedom propeller test platform suitable for a vertical circulating water tank and a test method. The three-degree-of-freedom propeller test platform comprises a rotation driving mechanism, a horizontal moving mechanism, a dynamic torque test mechanism, a propeller thrust test mechanism and a lifting control mechanism, the rotation driving mechanism, the horizontal moving mechanism and the dynamic torque test mechanism are all arranged on water, and a power source does not need to be sealed; the rotation driving mechanism changes the direction of force through a reverser and drives a horizontal shaft of the propeller thrust test mechanism to drive a propeller to rotate; the reverser, the horizontal shaft and the propeller are all of pure mechanical structures and are not affected when being placed underwater; a dynamometer is arranged on water to measure thrust; and the lifting control mechanism adjusts the underwater depth of the propeller thrust test mechanism. Therefore, the platform can test the thrust, the torque and the progress coefficient of the propeller corresponding to different depths and different rotating speeds under the vertical circulating water tank, and can well compare the correctness of commercial software.

Description

technical field [0001] The invention belongs to the technical field of test equipment, and in particular relates to a three-degree-of-freedom propeller test platform and a test method suitable for vertical circulating water tanks. Background technique [0002] The propeller is the most commonly used propulsion power device in the marine industry. The propeller rotates to provide power for the ship, and the motor provides the corresponding rotational speed to match the required torque and thrust. The propeller is the core part of the ship. With the development of marine resources by the Chinese government, the country has higher and higher requirements for the performance and efficiency of the propeller. [0003] The research on the hydrodynamic performance of the propeller is extremely critical. It can improve its performance and efficiency and break through key technologies. Not only is it of great significance to the development of my country's navy and the improvement of...
