Analytical and Experimental Modal Analysis of a Bladed Disk

Abstract

Abstract The conference paper discusses a study on the modal behavior of a bladed disk in rotating machinery system using analytical and experimental modal analysis techniques. The process involves measuring natural frequencies under different operating conditions. The modal properties from both approaches are compared, and the effects of rotational speed on the modal behavior of the bladed disk are presented and discussed. The analytical and experimental findings provide a comprehensive understanding of the bladed disk’s modal characteristics under varying rotational speeds. The integration of these different modal analysis techniques enhances the accuracy of the results and enables a more thorough investigation of the bladed disk’s behavior in rotating machinery systems.
