Fluid-Structure Interaction Forces at Pump-Impeller-Shroud Surfaces for Rotordynamic Calculations
(The American Society of Mechanical Engineers (ASME), 1989)Governing equations of motion are derived for a bulk-flow model of the leakage path between an impeller shroud and a pump housing. The governing equations consist of a path-momentum, a ... -
A Generalized Approach to the Dynamics of Cracked Shafts
(The American Society of Mechanical Engineers (ASME), 1989)A new analytic-experimental method for describing crack breathing and obtaining shaft local stiffness change is presented. A generalized nonlinear formulation using the finite element method, which ... -
Dynamic Sensitivity of Structures to Cracks
(The American Society of Mechanical Engineers (ASME), 1989)Cracks that develop on machine members and structures influence their dynamic behavior. The Rayleigh principle is used for an estimation of the change in the natural frequencies and modes of ... -
Analytical Results for Optimum Actively Damped Suspensions Under Random Excitation
(The American Society of Mechanical Engineers (ASME), 1989)A single degree-of-freedom system under white noise base velocity excitation is optimized using analytical expressions for mean square response quantities. In addition to a parallel spring and ... -
