Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The paper discusses the turbocharger turbine shaft critical speed calculations. Assuming floating bearing is a fixed bearing. Role in the turbine and the shaft of the axial force and torque are negligible. Each part of the shaft and shaft as the weight of the concentrated force act on the shaft. Without considering the temperature. Supporting structure of the turbine shaft is to simplify. Calculate the center of gravity and the axis of each part the focus of the shaft segment and synthesis of focus. Calculated stiffness of the shaft axis of the supporting structure according to simplified. Turbine shaft critical speed calculation applicates Dunkeley cumulative method.
