Abstract: A re-examination of rotor-bearing instability has led to a fresh approach that can potentially improve measurement accuracy of journal bearing rotordynamic coefficients. The approach uses a ...

Abstract: A time-transient nonlinear dynamic analysis is presented to study the motion of statically unloaded journal-bearing tilting pads. The major finding is that unloaded pads can exhibit a strong ...

Abstract: An analysis of a self-energized hydrostatic shaft seal operating with incompressible fluid in the laminar regime is presented. Dimensionless results are optimized for maximum stiffness. Comparisons ...

Abstract: Solutions were developed and are shown here for the primary laminar steady flow field that occurs in an incompressible, isoviscous, Newtonian fluid which is contained between two finite parallel ...

Abstract: Experimental determination of both steady-state and dynamic performance of a journal bearing requires the use of a high precision spindle with a vanishingly small range of run-out. This was ...

Abstract: This paper describes an experimental and theoretical investigation of a four-pocket, oil-fed, orifice-compensated hydrostatic bearing including the hybrid effects of journal rotation. The test ...

Abstract: The vibration of large turbomachinery blading is well known to be one of the most important design factors in modern turbomachinery. Typically, blade vibration is dominated by the unsteady flow ...

Abstract: There is currently a considerable interest and level of activity in developing computational schemes to predict general engine dynamic behavior. The general feeling among researchers working on ...
