Rotational speed oscillation characteristic and decomposition algorithm of torsional vibration
2008 7th World Congress on Intelligent Control and Automation, 2008For analysing the torsional vibration characteristic of rotary mechanical drive system, a new highly active calculation decomposition algorithm was proposed by using series decoupled method. When the elastic driving shaft and motor shaft had speed oscillation, the decomposition algorithm could develop nonlinear differential equation into a series of ...

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,

Free torsional vibration characteristics of compound planetary gear sets
Mechanism and Machine Theory, 2001A family of torsional dynamic models of compound gear sets is developed to predict the free vibration characteristics under different kinematic configurations resulting in different speed ratios. The compound gear sets considered consist of two planes of single- or double-planet gear sets connected by a straight long planet.

Free Torsional Vibration Characteristics of a Closed-Form Planetary Gear Set
Applied Mechanics and Materials, 2013A purely torsional dynamic model of closed-form planetary gear set is developed to investigate its natural frequency and free vibration modes. The closed-form planetary gear set considered consists of two-stage planetary gear connected by high-speed carrier and ring gear. Three identical planet gears are equally spaced in each stage.
