An Internal Resonance Based Method for Reducing Torsional Vibration of a Gear System

open access: yesMachines, 2022
The gear system is one of the most widely-used transmission systems due to its accurate transmission ratio and high efficiency. However, torsional vibration may severely degrade transmission performance and shorten the gear lifespan.

Radiative activity of magnetic white dwarf undergoing Lorentz-force-driven torsional vibrations

open access: yes, 2011
We study radiative activity of magnetic white dwarf undergoing torsional vibrations about axis of its own dipole magnetic moment under the action of Lorentz restoring force. It is shown that pulsating white dwarf can convert its vibration energy into the

Influencing the conductance in biphenyl-like molecular junctions with THz radiation [PDF]

open access: yes, 2013
We investigate the torsional vibrations in biphenyl-like molecular junctions and transport properties in the presence of an external THz field. Ab-initio calculations including external electric fields show that the torsional angle {\phi} of a thiolated ...

Experimental investigations on longitudinal-torsional vibration-assisted milling of Ti-6Al-4V

open access: yesThe International Journal of Advanced Manufacturing Technology, 2020
In vibration-assisted milling (VAM), an additional high-frequency oscillation is superimposed on the kinematics of a conventional machining process. This generates oscillations of the cutting edge in the range of a few micrometers, thereby causing a high-
