Problems solved by technology

At present, the test methods and procedures of its basic performance and parameters are mainly based on the test methods and procedures of ordinary motors, which is feasible to a certain extent, but there is currently no mature precedent for the promotion of motor reliability tests, which needs to be combined with UUV On-site testing of the equipment as a whole requires a huge investment in manpower, material and financial resources, and it is a one-time investment. The propulsion motors for different equipment need to be invested repeatedly

Embodiment 1

[0024] This embodiment provides a UUV propulsion motor reliability laboratory testing system, which is mainly used for the verification and assessment of the dynamic sealing performance of the underwater unmanned vehicle (UUV) watertight propulsion motor, and the reliability verification and assessment of the propulsion motor and its controller. It is used for reliability test and assessment of UUV watertight propulsion motor.

[0025] The reliability test of UUV propulsion motor refers to the full-load function test to detect whether it operates stably within the set time under full-load conditions and whether its mechanical and electrical parts can still meet the basic requirements of the propulsion motor after the stable operation. Performance index; if after the end of stable operation, its mechanical and electrical parts can still meet the basic performance index of the propulsion motor, its reliability is considered to meet the requirements.

Embodiment 2

[0039]On the basis of the above-mentioned embodiment 1, in order to simulate the operating environment of the propulsion motor of the underwater unmanned vehicle (UUV) more realistically and to make the test results more accurate, the water tank 8 is replaced with a closed pressure vessel to simulate the underwater stressful environment. The propulsion motor 17 to be tested is installed in the autoclave, and the autoclave is provided with a pressure gauge for real-time display of the internal water pressure value. The pressure in the autoclave can be adjusted through the cooperation of the water outlet valve 14 and the water inlet valve 18 to realize the test of different water depths. For example, by keeping the pressure in the autoclave at 1MPa, the environment of 100m underwater can be simulated to test the propulsion under test. Reliability of motor 17 when used in water depth of 100m.

Abstract

The invention provides a UUV propulsion motor reliability laboratory testing system and method, comprising: a DC stabilized power supply, a propulsion motor controller, an industrial computer, a generator, a water tank, a rectifier, an electronic load instrument and an installation base. The water tank contains an installation base, which provides a support installation and fixed space for the propulsion motor and generator under test. At the same time, the height of the water storage line inside the water tank can be adjusted according to actual needs through the water inlet valve and the water outlet valve to ensure the normal working environment of the watertight propulsion motor. The DC stabilized power supply is used as the energy equipment of the whole test system to provide power, and the industrial computer is used as the upper computer to send control instructions to the propulsion motor controller under test. During the test, the propulsion motor under test drives the generator as the load, and the three-phase rectifier converts the three-phase alternating current output by the generator into direct current, which is supplied to the electronic load instrument that provides the load for the propulsion motor under test.

Description

technical field [0001] The invention relates to a laboratory testing system and method, in particular to a laboratory testing system and method for reliability testing of an underwater unmanned vehicle (UUV) propulsion motor, and belongs to the field of electromechanical technology. Background technique [0002] my country is a large maritime country. Issues such as Taiwan, the South China Sea, and the East China Sea, as well as the security of maritime strategic passages need to be resolved urgently. As a sea power multiplier, underwater unmanned vehicles (UUV) have extensive and important military uses. In future naval warfare has an irreplaceable role. With the development of UUV and related technologies, UUV has been used to perform tasks such as mine clearance, reconnaissance, intelligence collection, and ocean detection. It may also be used as an underwater weapon platform and logistics support platform in future naval warfare, so it is of great significance. . [000...
