Abstract :
Critical vibration has an important influence to the reliability of newly developed hybrid turbocharging system. In this paper, the finite element method is adopted to research the rotor dynamics of hybrid turbocharging system in a vehicle engine, the model is established to simulate the critical vibration of hybrid turbocharging rotor, and the main kinematic equations of the model are given. Then the critical speed and vibration amplitude map of 3 orders are obtained by critical vibration simulation about the hybrid turbocharging rotor. In the end the vibration amplitude and vibration acceleration are experimented in the bench test, and the test result shows that the error of critical vibration by finite element method is less than 5%. The experiment data confirms that the simulation using the finite element method is effective to the critical vibration of hybrid turbocharging rotor.
