Measurement method of torsional vibration signal to extract gear meshing characteristics [PDF]
Journal of Vibroengineering, 2018 A technique in measuring torsional vibration signal based on an optical encoder and a discrete wavelet transform is proposed for the extraction of gear meshing characteristics. The method measures the rotation angles of the input and output shafts of a gear pair by using two optical encoders and obtains the time interval sequences of the two shafts. By

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

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

Torsional vibration characteristics analysis of DFIG‐based wind farm and its equivalent model [PDF]
IEEJ Transactions on Electrical and Electronic Engineering, 2017 As large‐scale wind farms (WFs) are integrated with the power grid, the interaction between the WF and the grid may excite torsional vibration of the shaft of the wind turbine. To study the shaft's torsional vibration characteristics of a doubly fed induction generator (DFIG)‐based WF, a detailed small‐signal model of DFIG is established first.

Study on Vibration Characteristics through Torsion Spring Constants within Automobile Muffler
Indian Journal of Science and Technology, 2015 In the present study, torsion springs with different spring tensions were designed and produced, and a study was conducted concerning what effects vibration occurring in an exhaust variable valve has on engine performance and back pressure. Therefore, it will be affirmed by designing and producing torsion springs with different spring tensions in the ...
