Proceedings Papers

Proc. ASME. GT2020, Volume 10A: Structures and Dynamics, V10AT25A020, September 21–25, 2020
Paper No: GT2020-15008
... when journal eccentricity can’t be neglected while simulating hydrostatic bearing characteristics. Simulations also allow for analysis of how different design/geometrical parameters and initial conditions (supply pressure) influence bearing performance characteristics. The developed approach can...

Proc. ASME. GT2010, Volume 6: Structures and Dynamics, Parts A and B, 11-23, June 14–18, 2010
Paper No: GT2010-22058
... allows determining direct and cross-coupled stiffness coefficients of the seal by integrating measured circumferential pressure distribution in cavities at various shaft eccentric positions. In the dynamic method, identification of stiffness and damping coefficients is based on the rotor excitation using...

Paper No: GT2009-59450
... 23 02 2010 “MICE” is an acronym for Misalignment, Imbalance, Crack and Eccentricity. These form the most catastrophic faults in rotor shafts of gas turbine engines that could lead to downtime. This paper therefore enunciates steps to early detection of these faults and how they could...
