Abstract: A simple pendulum whose pivot executes harmonic motion in the vertical direction is a prototype for systems subjected to parametric excitation. Forced excitation of this system is represented ...

Abstract: The Algorithm of Mode Isolation (AMI) extracts modal properties from complex frequency response data. Previous work used classic undamped modes as the analytical framework for the algorithm. The ...

Abstract: A shaft with attached rigid disks is modeled as a rotating Timoshenko beam supported by nonconservative, flexible bearing supports. The continuous shaft-disk system is described with kinetic and ...
