A review of analyses related to vibrations of rotating piezoelectric bodies and gyroscopes
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2005A 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, 2003In 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

Transient vibrations of a beam/mass system fixed to a rotating body
Journal of Sound and Vibration, 1986Abstract Transient flexural vibrations of a beam/mass system fixed to a rotating body are investigated. The rotating body is driven so as to have a velocity profile of trapezoidal shape. The governing ordinary differential equations of the beam mass system are derived by use of the extended Galerkin method, and the transient response is obtained by ...

Analysis of automobile engine cylinder pressure and rotation speed from engine body vibration signal
SPIE Proceedings, 2016In order to improve the engine vibration signal process method for the engine cylinder pressure and engine revolution speed measurement instrument, the engine cylinder pressure varying with the engine working cycle process has been regarded as the main exciting force for the engine block forced vibration.

The free vibration and buckling of a rotating annular plate with constant angular speed free at the inner edge and fixed at the outer edge subjected to a compressive centrifugal body force are analyzed using the Ritz method. Exact stress components and radial displacement of the rotating annular plate are obtained via the plane elasticity. Convergence

Method for contactless measuring of vibrations of a rotating body
2002Stationary sensors are used to measure periodically the vibratory motions of portions of a body spinning in front of them, such as blades, and to try to determine their natural frequencies by spectral analyses. The sensors are collected together in several networks of different numbers and the determination includes a comparison of the spectra of the ...

Journal of Sound and Vibration, 2002
Abstract The effect of variations in posture and vibration magnitude on apparent mass and seat-to-pelvis pitch transmissibility have been studied with vertical random vibration over the frequency range 1·0–20 Hz. Each of 12 subjects was exposed to 27 combinations of three vibration magnitudes (0·2, 1·0 and 2·0m/s2 r.m.s.) and nine sitting postures ...
