Simulation and Test of Torsional Vibration of Compressor for a Continuous Transonic Wind Tunnel arecarriedout to meet the requirement of researchontheexcitationmechanismandrestraintmethod.The parametersofthecompressorshafting areusedto-modelandsimulate,andthetorsional modesandrotationalspeedoffirst tofourthorderareobtained.The dataof torque amplitude,torsiona-langle androtatespeed aregottenbyusingthetestmethodofwirelessstraintorquetestandgeardisk-eddycurrenttest.The test results show that the data getting by simulating,wireless strain torque test and gear disk-eddy current test havegoodconsistency,andallthethree approaches arefeasible.The data of analysis and test can be an important reference for the subsequent experimental verification of the excitation mechanism and restraint method.
