Large-power fuel pump on-load vibration test system

The invention discloses an on-load vibration test system for a high-power fuel pump, and belongs to the technical field of aero-engine tests and tests.The fuel pump is fixed to a vibration unit through a vibration clamp, the vibration clamp has a transmission function, and the function of synchronous transmission of vibration parameters, torque and rotating speed of a high-power fuel pump regulator under all working conditions is achieved; the vibration unit is connected with the vibration clamp through a flexible shaft, and the fuel pump is fixed to the vibration clamp and connected with the fuel unit through a metal hose. The flexible shaft is used, vibration displacement compensation under different working conditions is achieved by adjusting the number of the elastic elements, and the transmission problem of specified torque and rotating speed under the working state vibration test of the high-power and high-rotating-speed fuel pump regulator is solved. The material of the coupling is improved, so that th
