Proc. ASME. IJTC2012, ASME/STLE 2012 International Joint Tribology Conference, 217-219, October 7–10, 2012
Paper No: IJTC2012-61041
.... This paper documents a new, modified tilting pad bearing concept that has replaced the fixed geometry bushings with minimal modifications to the stock bearing housing. The summary of the on-engine testing over the past year is documented in this paper. turbocharger analysis experimental stability...

... 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...

... perturbation technique. The linear stability of the system [6, 8] is evaluated by solving the eigenvalues problem for the homogeneous dynamic equation of motion based on the linear bearing characteristics. The transient motion of the rotor is calculated by numerically integrating the velocity and displacement...
