Application of Dynamic Fractional Differentiation to the Study of Oscillating Viscoelastic Medium With Cylindrical Cavity
(The American Society of Mechanical Engineers (ASME), 2002)Oscillations of a viscoelastic medium with a cylindrical cavity are studied. The viscosity is taken into account in the form of an additional term in the constitutive equation, proportional to ... -
Ritz Series Analysis of Rotating Shaft System: Validation, Convergence, Mode Functions, and Unbalance Response
(The American Society of Mechanical Engineers (ASME), 2002)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 ... -
Discrete Frequency Models: A New Approach to Temporal Analysis
(The American Society of Mechanical Engineers (ASME), 2001)Forced vibration responses of nonlinear systems contain harmonics of the excitation frequency. These harmonics are either directly forced or are subharmonic, superharmonic, or combination resonances. ... -
On the Modal Testing of Microstructures: Its Theoretical Approach and Experimental Setup
(The American Society of Mechanical Engineers (ASME), 2001)Small and lightweight structures have very high natural frequencies and small elastic displacement compared to ordinary structures. Due to limited excitation bandwidth and relatively large size ... -
