Torsional Vibrations of Nonhomogeneous
ABSTRACT. This paper is concerned with the torsional vibrations of a nonhomogeneous magnetostrictive elastic cylinder. The cylinder is subjected to the action of a circumferential magnetic field produced by an axial current of constant density and the deformation of a magnetostrictive cylinder is produced by a constant longitudinal magnetic field. The frequency equation is determined, and the d...
متن کاملPower Electronic Devices for Damping Torsional Vibrations
Torsional vibrations and resonance problems with synchronous machines are most frequently encountered in rotor systems with long shafts and large inertias constituting a weakly damped mechanical resonator which exhibits a low resonance frequency. It is impossible to obtain a effective mechanical damping for these torsional vibrations, but by using a power electronics device and an inductive or ...

متن کاملDetermination of the Viscoelastic Shear Modulus Using Forced Torsional Vibrations
Many methods exist for the experimental determination of the viscoelastic properties of materials. Some of these methods have been summarized [1,2]' and those that have been used more recently appear in a collection of abstracts [3]. The method described herein, which uses forced torsional vibrations, is an updated version of previous works [4,5]. It was selected because it most easily met the ...
متن کاملMitigation of Train-Induced Floor Vibrations in Multi-Story Buildings Using a Blocking Floor
A new method is developed for reducing train–induced floor vibrations in buildings. Vibration transmitted through building columns to the upper floors can be mitigated by considerably increasing the thickness of a lower floor, which is named the “blocking floor”. This can be a desirable and inexpensive solution for vibration mitigation. The work presented by this paper shows the ability of an i...
