The Journal of the Acoustical Society of America, 1982
The disclosure illustrates a tuned viscous torsional vibration damper having a hub member for attachment to an internal combustion engine crankshaft. An annular inertia mass is journaled within the hub member to form a working chamber which contains a viscous liquid to damp out torsional oscillations of the inertia member relative to the hub.

A torsional vibrations problem
Electrical Engineering, 1958TORSIONAL vibration studies of simple mechanical systems are usually handled by methods which, while not difficult, often require the expenditure of considerable time when done by hand. The use of a digital computer shortens the time considerably. One method frequently used is the Holzer table calculations resulting in the determination of the natural ...

Torsional Sensors for Conical Shell in Torsional Vibrations
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2010This paper presents shear piezoelectric sensors for conical shell sensing. The piezoelectric patch is polarized in the longitudinal direction of conical shell structure. The electrodes are fixed at the sides parallel to the directions of polarization. Sensors in this arrangement are only sensitive to the in-plane shear strains.

On the Torsional Vibrations of Long Chain Molecules
Proceedings of the Physical Society. Section B, 1952Simplified models are discussed for long chain molecules in which all units are equal except for one which is heavier than the others. Certain general conclusions are reached for the vibrations of such molecules. The results will be applied to the out-of-plane or torsional vibrations of long chain ketones in a following paper.
