Abstract

The invention relates to a loading test apparatus for simulating a ship thruster. The loading test apparatus comprises a propeller simulation block, an axial static thrust loading device, a dynamic force loading device, torque loading devices and a three-component dynamic force measuring device. The propeller simulation block is installed at the tail end of a propeller shaft screw shaft; the axial static thrust loading device is connected with the propeller shaft to realize axial force transmission; the dynamic force loading device can load dynamic forces along axial and radio directions; the torque loading devices are arranged at the two sides of the propeller shaft symmetrically and transmission between the torque loading devices and the propeller shaft is realized by a narrow V-band mechanism; and the three-component dynamic force measuring device can measure practical dynamic force component force values transmitted to X, Y, and X directions of the propeller shaft. With the test apparatus provided by the invention, various loads in mutual interaction between the propeller and the propeller shaft during the ship operating process can be simulated comprehensively; and loading of an axial static thrust, a dynamic force, and a torque can be realized.

Description

technical field

[0001] The invention relates to a loading test device for simulating a ship propeller. Background technique

[0002] The power from the main engine of the ship is transmitted to the propeller, which makes the propeller rotate, and at the same time, the thrust generated by the propeller rotation is transmitted to the hull through the thrust bearing to push the ship to sail. In this complex process, the propulsion motor transmits torque to the propeller, and at the same time, the propeller transmits static thrust through the propulsion axial thrust bearing, and because the propeller rotates in the uneven flow field at the stern, there is still unsteady thrust Component, thereby inducing the vibration of the propulsion shafting of the ship, causing the vibration of the hull and generating radiated noise.

[0003] At present, relevant domestic universities and scientific research institutions have established some loading test devices for simulating ship propell...
