VTechWorks staff will be away for the Thanksgiving holiday beginning at noon on Wednesday, November 22, through Friday, November 24, and will not be replying to requests during this time. Thank you for your patience, and happy holidays!
Dynamic Stability Evaluation of an Automotive Turbocharger Rotor-Bearing System
This project was initiated to more fully understand the dynamic stability of an
automotive turbocharger rotor-bearing system using both linear and nonlinear analyses.
The capabilities of a commercial Finite Element Analysis (FEA) code (computer
program) were implemented in the investigation process. Several different hydrodynamic
journal bearings were employed in the study of the turbocharger linearized dynamic
stability. The research demonstrates how the linear analysis of a turbocharger
rotordynamics can be very beneficial for the design evaluation and maintenance
