| Abstract: | In this paper,the stablility of floating-ring bearing-rotor system of the turbocharger is studied by both experiment and simulation.First,the rotional speed of floating-ring bearing and the shaft motion are measured by the eddy current displacement sensor,by which the qualitative analysis is carried out.And then the simulative method is used for quantitative analysis for different inner and outer gaps of bearing,by which the qualitative analysis result is verified.The results can provide technical support f... |
