【Abstract】 Basedontheconstructionof ENN1500 gas turbine test bench, the characteristic curve of hydraulic dynamometer is discussed. The selection method of hydraulic dynamometer, the design requirements of water system and the PID adjustment method of hydraulic dynamometer control are given. The rotational torque sensor is discussed. The measurement principle is given, and the selection method and installation and use requirements are given. At the same time, the measurement and control system platform based on PXI and LabVIEW is designed. The test shows that the equipment works well and meets the requirements of gas turbine test.更多还原
