| In order to test the performance of the fuel metering component of the aeroengine exactly，，the control system of the
performance test was studied. The hydraulic control system was designed based on the structure，working principle and test requirements of
the fuel metering component. The displacement servo control system composed of servo motor，lead screw and grating sensor was used to
realize the precise control of the valve core displacement of the metering component. The control strategy of "compound control of pump and
valve+ coordinated control of inlet and outlet pressure"was put forward，so as to realize the precise control of the outlet pressure and the
pressure difference of the inlet and outlet of the metering component. The results show that the displacement control accuracy of the valve
core of the fuel metering component can reach ±0.001 mm. The control accuracy of post pressure and pressure difference before and after
metering component can reach ±0.002 MPa. The performance test control system of fuel metering component can meet the requirements of
performance test. |
