... be very reliable if drifts are removed. Second observation — In a system with significant rubs during dynamic test, it is commonly observed that vibration response contains frequencies of multiple orders of fundamental excitation frequency. Vibration at multiple orders is localized to the rubbing zone...

... Abstract As the variable energy sources become predominant in the energy mix, power system stability and resiliency have become the topics of prime research. Grid connected or island systems face similar challenges for multiple applications like frequency control, economic dispatch, peak...

... Abstract Controversy regarding the dynamic modeling of tilting-pad journal bearings (TPJB) has existed for years, with the question of the effective stiffness and damping properties, and the requirement for consideration of frequency dependency, being of great concern. There is a partial...
