In-plane vibration of a rigid body attached to a flexible rotating beam

Journal of Sound and Vibration, 2020
Abstract The dynamics of rotating systems are conventionally analyzed using models that assume the axis of rotation to be stationary. However, in instances such as helicopters and gas turbines with contra-rotating rotors such models which neglect the complexity arising from the coupling between the stator and the rotor due to their comparable masses ...

Vibrations of rapidly rotating N-body systems

Chemical Physics Letters, 1990
Abstract A generalization of the Eckart scheme applicable to N-body systems with arbitrarily large angular velocities is formulated. Its virtue is that it explicitly accounts for centrifugal distortions. As a consequence, it leads to angular momentum-labeled fundamental frequencies of oscillations.

Space-fixed formulation for the vibration of rotating, prestressed, axisymmetric bodies and shells

Journal of Sound and Vibration, 2021
Abstract The vibration of high-speed, rotating, three-dimensional, flexible, axisymmetric bodies coupled to stationary structures motivates this work. Exploiting the axisymmetry of the body, a semi-analytical model is developed that only discretizes the two-dimensional radial cross-section; Fourier series are used in the circumferential direction ...

A many‐body diagrammatic theory of rotation–vibration spectra

International Journal of Quantum Chemistry, 1989
AbstractA many‐body diagrammatic perturbation theory of rotation–vibration spectra is elaborated. The present approach is based on two many‐body techniques, namely on the second quantization formalism (a rotating–vibrating molecule is formally treated here as a system of interacting vibrons, obeying the Bose–Einstein statistics) and the many‐body ...

Rotating body sympathetic vibration absorber

The Journal of the Acoustical Society of America, 1986
In a vibration absorber for resonance vibrations of rotating bodies, in particular rail wheels, comprising several oscillatory plates which establish a damping mass; intermediate layers of damping material separating the plates from each other; a fastener connecting the plates with the rotating body at at least one point and an intermediate layer of ...

A review of analyses related to vibrations of rotating piezoelectric bodies and gyroscopes

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2005
A review of analyses on vibrations of rotating piezoelectric structures for applications in piezoelectric angular rate sensors is presented. The operating principle and the basic behaviors of piezoelectric gyroscopes are shown by a simple example. Structural shapes and vibration modes that can be used to make gyroscopes are summarized.

Biaxial Vibrations of an Elasto-Plastic Beam With a Prescribed Rigid-Body Rotation

Volume 5: 19th Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2003
In the present work, the development of plastic strains in a flexural beam is studied. The beam is modeled as a Bernoullieuler beam, where large rigid-body rotations and biaxial bending in the small strain regime are studied. The deformation is split into the spatial deformation of a hinged-hinged beam and the movement of the second support. Neglecting
