Research on dynamic behavior of ball bearing-rotor system with damper for turbocharger
In order to study the effect of supporting structure on power performance of ball bearing turbocharger, the FEM model of ball bearing rotor system with damper is established. Considering the effect of damper on bearing stiffness of rotor system, the analyses of critical speed, imbalance response and axes track for rotor system with and without damper are carried out. The results show that damper can adjust the critical speed of rotor system after changing the total bearing stiffness of rotor system .According to the analyses of imbalance response and axes track, the effect of damper to restrain vibration of rotor system is obvious. Based on the verification test, the analysis results are found to be in reasonable agreement with the test results.
