Counter torque control of torsional vibration suppression device using permanent magnets
A periodic reversal spring (PRS) with permanent magnets is proposed to suppress the torsional vibration of automobile powertrains. Results of numerical dynamic simulations pertaining to automobile powertrains from a previous study show that the magnetic ...

Flexural–torsional buckling of thin-walled composite box beams [PDF]
Buckling of an axially loaded thin-walled laminated composite is studied. A general analytical model applicable to the flexural, torsional and flexural–torsional buckling of a thin-walled composite box beam subjected to axial load is developed.

Coupled tension-torsion vibration of repetitive beam-like structures [PDF]
Equivalent continuum stiffness properties, derived from the eigenanalysis of a single cell of a planar beam-like repetitive structure, have previously been employed within well-known dynamic theories, such as Euler–Bernoulli and Timoshenko for flexural ...

Parametric resonance of a nonlinear energy harvester for torsional vibrations [PDF]
Torsional vibrations occur commonly in power transmission systems and components. Often these vibrations are subject to transient frequency response, which are nevertheless dominated by fixed multiples of the main shaft speed (such as engine order ...

Torsional Vibration Suppression in Railway Traction Drives
Torsional vibrations phenomena are self-excited vibrations that occur in the wheelset of railway powertrains due to the counter-phase oscillation of both wheels. Long-lasting events of this type may lead to the catastrophic failures. Therefore, torsional

Development of a torsional vibration suppression device using permanent magnets
Dual mass flywheel (DMF) dampers are conventionally used for torsional vibration suppression in automobile powertrains. The torsional vibration in powertrains has increased in recent years owing to the widespread downsizing of internal combustion engines
