Longitudinal and Torsional Vibration Characteristics of Boron Nitride Nanotubes
Journal of Vibration Engineering & Technologies, 2019Boron nitride nanotubes (BNNTs) are new cousins of carbon nanotubes (CNTs), which alternately substitute boron and nitrogen atoms for carbon atoms entirely. Its excellent physical and chemical properties, such as excellent thermal stability, chemical inertness and strong acid corrosion resistance, make BNNTs products be favorable to machine, thus ...

Characteristics of torsional vibrations of a shaft with unbalance
Journal of Sound and Vibration, 2007The aim of this paper is to study the characteristics of torsional vibration of a rotor with unbalance by numerical simulation. It can be concluded that synchronous torsional vibration accompanying with small higher harmonic components are excited, except when the speed of rotation is near, or equal to, half the natural frequency of torsional vibration,
