Abstract

The invention discloses an underwater thruster testing device, which adopts a coupling to simultaneously measure the thrust and pulling force of the thruster, and arranges a pressure sensor in a sealed box. When testing, the pressure sensor is placed underwater to directly receive the thruster. At the same time, the device can greatly weaken the influence of turbulent flow generated by the propeller and improve the test accuracy. The device has the advantages of simple structure, small volume, no need for multiple installations, high applicability, low cost and convenient operation.

Description

technical field [0001] The invention belongs to the field of underwater testing, and more particularly relates to an underwater thruster testing device. Background technique [0002] Underwater thrusters, also called underwater boosters, are the power source for most underwater robots. The correct establishment of the propeller model is of great significance to the control of underwater robots, so it is necessary to obtain more accurate thrust parameters of the propeller. [0003] At present, the mainstream thrust testing devices mostly adopt the principle of lever, that is, the underwater thruster and the thrust sensor are placed at both ends of the lever, the midpoint of the lever is hinged to the rotating shaft, and the thrust of the thruster is measured by the principle of isometric arm. This testing device has complex structure, large volume and low testing precision. In addition, because most of the tests are carried out in limited waters, the turbulence generated by...
