This paper presents the effect of tilt angle on static and dynamic performance characteristics of two gas-lubricated noncircular journal bearing configurations, namely two and four lobe bearings. The linearized system approach using finite element method is used to obtain both steady state and dynamic characteristics.
The results of the investigation show that tilt angle has a significant effect on static and stability characteristics. With an increase in tilt angle, power loss is decreased while stability margins are increased.
