Experimental investigation of torsional vibration isolation using Magneto Rheological Elastomer
MATEC Web of Conferences, 2018 Rotating systems suffer from lateral and torsional vibrations which have detrimental effect on the roto-dynamic performance. Many available technologies such as vibration isolators and vibration absorbers deal with the torsional vibrations to a certain ...

New definition for torsional irregularity based on floors rotations of reinforced concrete buildings
Journal of Engineering and Applied Science, 2022 Earthquake investigations confirm that un-symmetric buildings suffer more damage than their symmetric counterparts. Torsional vibrations due to irregularity are one of the main factors which cause damage to buildings.

Torsional Vibrations in a Crank Shaft [PDF]
, 1991 In this paper, we analyze the torsion in the crank shaft of a gas compressor with one crank. The effect of damping will not be studied here. The geometry is as drawn in Fig. 1. Two forces are exerted on the shaft. First, it is at one end driven by a motor.

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]
, 2010 Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.

Special devices for reducing the amplitude of torsional vibrations crankshafts [PDF]
, 2023 Torsional vibrations are observed in all mechanisms that involve rotational movement of shafts. For internal combustion engines, the problem of torsional vibrations of the crankshaft is relevant, since significant vibrations prevent its fatigue failure ...
