Resonant characteristics of rectangular microcantilevers vibrating torsionally in viscous liquid media [PDF]
2012 IEEE International Frequency Control Symposium Proceedings, 2012 The resonant characteristics of rectangular microcantilevers vibrating in the torsional mode in viscous liquid media are investigated. The hydrodynamic load (torque per unit length) on the vibrating beam due to the liquid was first determined using a finite element model.

Torsional vibration characteristics of power transmission system
IOP Conference Series: Materials Science and Engineering, 2018 Torsional vibration is a frequent perturb for heavy rotating and high speed machinery. Development of large torsional vibrations produce torsional stresses which leads to increase in bearing loads and results in generation of cracks in the high stress areas of the transmission system and propeller. So, it is important to model and analyze the torsional

Bifurcation characteristics of torsional-horizontal coupled vibration of rolling mill system [PDF]
Journal of Vibroengineering, 2017 In this paper, the static bifurcation and dynamic bifurcation of rolling mill system with torsional-horizontal coupling vibration are studied. Firstly, the dynamic equation of torsional-horizontal coupled vibration of rolling mill main drive system is established. Rolling mill is driven by the gear pair, so the torsional vibration of the gear pair, the
