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.

Nonlinear torsional vibration characteristics of PMSM for HEV considering electromagnetic excitation
International Journal of Applied Electromagnetics and Mechanics, 2015Permanent magnet synchronous motor is an electromechanical coupled system. Electromagnetic field can result in change of the dynamic behaviors of the PMSM's rotor system. Here, changes to the electromagnetic torque excitation caused by the torsional displacement are considered using electromechanical coupled dynamic equations for the rotor.

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.

FLEXURAL–TORSIONAL COUPLING EFFECT ON VIBRATIONAL CHARACTERISTICS OF ANGLE-PLY LAMINATES
Journal of Sound and Vibration, 1998Abstract A mainly experimental investigation is presented on the vibrational characteristics of angle-ply laminate made of carbon/epoxy composite material, considering the effect of flexural–torsional coupling stiffness. This consists of a resonance test on a cantilevered laminated plate model by using laser holographic interferometry.

Characteristics of Torsional Vibrations of a Shaft System with Parallel Misalignment
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2005Couplings are important parts in the movement of a shaft system. A coupling can transfer the torque from one shaft to another through deforming itself. If parallel misalignment exists, the couplings will produce an extra deformation besides the deformation produced by transferring the torque.
