Critical Speeds of Continuous Shaft-Disc Systems.The critical speed of a rotor consisting of a single disc on a solid shaft is investigated. Since the disc radius to shaft radius ratio is assumed to be considerably small, the disc is treated as a beam element. Euler-Bernouli beam theory is used in the analysis. Furthermore, the gyroscopic and rot

A Theoretical Study into the Effects of Damped Flexible Foundations on the Dynamic Behaviour of a 66rformance of rotating machines. The dynamic behaviour of a 660MW LP steam turbine with various foundation characteristics has been analysed in the present study. Interesting results were obtained and these results may be useful in understanding the dynamic behaviour of similar machines.

These non-symmetric properties arise from the preferred direction of rotation of the rotor and by virtue of such features as internal damping forces, gyroscopic moments and forces from journal bearings, seals and other hydraulic and aerodynamic elements.

Modal Testing Techniquesery. Modal testing embraces the processes involved in the construction of a mathematical model of a structure from test data and over the past 10–15 years, the technology has been developed and used extensively on structures of all types. Although there are particular problems associated with the vi
