... that would allow the bearing to have less side leakage and higher performance. This paper will introduce a newly developed concept for a tilting segment bearing to replace the current stock floating ring bearing. Analysis of this new bearing shows great promise of improved stability. The result...

... of the rotor bearing design for these systems. In this research a commercial rotordynamics computer program is used to evaluate the stability and transient response of a high speed automotive turbocharger. Various models with varying bearing designs and properties have been solved to obtain the linear...
