Abstract

The invention discloses a high-pressure fluid pulsation control test platform, which comprises a test bed, a servo motor, a torque sensor, an axial plunger pump and a fluid pulsation control device; the servo motor, the torque sensor and the axial plunger pump are sequentially arranged, and the servo motor is connected with the torque sensor through a transmission shaft; the torque sensor is connected with the axial plunger pump through a transmission shaft, the high-pressure output end of the axial plunger pump is connected with the input end of the fluid pulsation control device through a pulsation high-pressure pipeline, the output end of the fluid pulsation control device is connected with the input end of the stable high-pressure pipeline, and the output end of the stable high-pressure pipeline is connected with a load. A front pressure transmitter is arranged on the pulsating high-pressure pipeline, a rear pressure transmitter is arranged on the stable high-pressure pipeline, andthe front pressure transmitter and the rear pressure transmitter are both electrically connected with the data acquisition instrument. By means of the impedance composite principle, the problems of fatigue damage of high-pressure pulsation to a hydraulic system and the like can be solved, and the operation stability of the device is improved.

Description

technical field [0001] The invention relates to a control test platform, in particular to a high-pressure fluid pulsation control test platform. Background technique [0002] The document "Fuel Tank Noise Measurement Drive Test Bench (CN201710689903.9)" discloses a fuel tank slosh noise measurement drive test rig. This invention can effectively measure liquid sloshing noise, but the vibration noise is in a low-pressure state. High-pressure fluids are widely used in hydraulic transmission fields such as flight control systems, underwater vehicles, excavator actuator drive systems, diesel engine fuel injection systems, and fuel cell hydrogen storage devices. As the power density requirements continue to increase, so does the pressure on hydraulic systems. The impact of high-pressure fluid, especially high-pressure pulsating fluid, on the pipeline will cause vibration, noise, fatigue damage, and affect the safety and reliability of the system. [0003] Conventional fluid puls...
