Abstract: A model consisting of n five-degree-of-freedom subsystems has been developed to characterize some of the mechanical response features of a bladed disk system, including four modes of each blade, ...

Abstract: This paper examines the application of matrix transformations from the experimentally obtained receptance matrix to the dynamic stiffness matrix to determine changes of blade stiffness and/or mass ...

Abstract: A resonant beam tuned damping device, comprising a flexible beam joined by way of visco-elastic links at the ends, to a vibrating structure, is described. This device has the advantage of ...

Abstract: This paper reports the results of a preliminary investigation of the feasibility of reducing vibratory response levels in jet engine turbine blades by means of tuned damping devices incorporating ...
