Research on the Verification Method of the Rotor Dynamics Model of the Locomotive Turbocharger

The reasonable establishment of rotor dynamics model is very important in the study. This paper establishes a dynamic model of the rotor, and gets the numerical calculation of the frequencies and mode shapes of the rotor under the free condition. The modal of the rotor bearing system is analyzed by using software. Compared to the above two kinds of results, the test of turbocharger rotor mechanics correctly modeled is to prove that this method has practical significance.
