IET Renewable Power Generation, 2023 Incidents of sub‐synchronous oscillations (SSOs) reported in the Hami power network of western China indicate that the torsional dynamics of a synchronous generator (SG) can be excited by a grid‐connected wind farm and trigger torsional SSOs. The concept

Flexural-torsional behavior of thin-walled closed-section composite box beams [PDF]
, 2007 This paper presents a flexural–torsional analysis of composite box beams. A general analytical model applicable to thin-walled box section composite beams subjected to vertical and torsional load is developed.

Effects of finite sizes of atomic nuclei on shear modulus and torsional oscillations in neutron stars [PDF]
, 2022 The shear modulus of neutron star matter is one of the important properties for determining torsional oscillations in neutron stars. We take into account the effects of finite sizes of spherical nuclei on the shear modulus and examine the frequencies of ...

The Individual Drive of a Wheelset and the Problematics of Its Electromechanical Phenomena
VehiclesThis paper deals with the phenomenon of torsion oscillations in railway vehicle drive systems. The main goal is to reduce the risk of presence of torsional oscillations in wheelset drive, eventually to propose systems to effectively identify and ...

Selfsimilarity relations for torsional oscillations of neutron stars
, 2022 Selfsimilarity relations for torsional oscillation frequencies of neutron star crust are discussed. For any neutron star model, the frequencies of fundamental torsional oscillations (with no nodes of radial wave function, i.e. at n=0, and at all possible

TORSIONAL OSCILLATIONS OF A MAGNETAR WITH A TANGLED MAGNETIC FIELD* [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT Motivated by stability considerations and observational evidence, we argue that magnetars possess highly tangled internal magnetic fields. We propose that the quasi-periodic oscillations (QPOs) seen to accompany giant flares can be explained as torsional modes supported by a tangled magnetic field, and we present a simple model ...

Dynamics of transformation of ultrasonic vibrations in twisted waveguides
MATEC Web of Conferences, 2018 The effective use of ultrasound energy in various technological processes largely depends on the type of ultrasonic vibrations. Wide application in practice has found longitudinal ultrasonic fluctuations in connection with simplicity of realization, and ...
