Abstract

The dynamic stability of an automotive diesel engine turbocharger rotor-bearing system was studied. The predicted whirl speed map indicated two modes of instability and was very similar to on-engine test results conducted at Virginia Tech as part of a senior capstone design project. The first one was likely a rigid body conical mode shape, where the compressor and turbine wheels moved in forward whirl but out of phase. The second whirl mode likely had a cylindrical mode shape with slight bending in the shaft, where the turbine and compressor wheels moved in forward whirl and in phase. The development of the diesel engine test stand and the associated data acquisition system were described. The turbocharger exhibited sub-synchronous vibration and self-exited instabilities. The onset of both modes occurred in each of the engine testing conditions, unloaded and fully loaded. This is an abstract of a paper presented at the STLE - 62nd Annual Meeting (Philadelphia, PA 5/6-10/2007).
