A methodology has been developed for the vibration analysis of spinning turbomachinery blades. A generalised program has been developed for the calculation of natural frequencies and mode shapes of a blade spinnnig under various boundary conditions. An equation has also been developed for the rapid estimation of natural frequencies of a spinning blade.

Abstract


A methodology has been developed for the vibration analysis of spinning turbomachinery blades. A generalised program has been developed for the calculation of natural frequencies and mode shapes of a blade spinnnig under various boundary conditions. An equation has also been developed for the rapid estimation of natural frequencies of a spinning blade.
