Design of Laboratory Dynamic Balancing Device and Investigation of Vibrations of Rotating Bodies

Journal of Engineering Technology and Applied Sciences, 2021
The rotor part to be balanced is mounted on the balancing device using a suitably designed fixture. When the rotor is rotated around its own axis, static and dynamic unbalance in the rotor, static and dynamic bending, which are simple harmonic movements in nature, cause oscillating motion.

On the plane strain in a theory for self-gravitating elastic configuration with initial static stress field

Annals of Geophysics, 1974
This paper is concerned with the plane strain in a theory for an arbitrary, uniformly rotating, self-gravitating, perfectly elastic Earth model with a hydrostatic initial stress field. Using the associated matrices method, a representation
