“…In their analysis of the forced vibration of a rotating tapered composite shaft, Kim et al (2001) introduced an equivalent viscous damping coefficient to account for external and internal damping. In a similar approach, the effect of internal and external viscous damping on the stability of a rotating shaft driven through a universal joint has been investigated by Mazzei and Scott (2003). In both cases, no damping treatment has been introduced.…”

A mathematical model, based on Timoshenko beam assumption, for a rotating cylindrical shaft with cylindrical constrained layer damping treatment is developed. The model is developed for a shaft made of composite materials, and treated with a cylindrical constrained layer damping partially covering the length span of the shaft. The discrete equations of motion are developed using two methods: the finite element method and the assumed mode method. The developed equations are applied to study the effect of some geometric and material parameters on the flexural stiffness and damping of the shaft, with emphasis on the coverage length of the cylindrical constrained layer treatment. The effect of the spinning speed is also considered. Initial results indicate that, for the special case covered in this paper, the finite element method renders accurate results, while the assumed mode method engenders erroneous results. The results, in general, conclude that the partial cylindrical constrained layer damping treatment, suggested in this paper, is not promising.

“…It turns out that a moment component normal to the shaft is unavoidable. T. Iwatsubo [3], A. J. Mazzei [4] and H. Ota [5] also investigated the moments transmitted by a universal joint before they modeling the motion equation of shaft driven by a universal joint. M. Kato [6] and P. P. Sheu [7] studied the transmitted moments in the shaft system driven by a universal joint with friction regarded and in the shaft system driven by two universal joints respectively.…”

Abstract. The moments transmitted by a universal joint in varying operating condition was investigated. A model of shaft system driven by a universal joint which consists of a driving shaft, a driven shaft and a cross piece is chose. Both structure misalignment and error misalignment between the two shafts at the universal joint was considered, and the study was based on the assumption that friction, inertia and elastic forces of the cross piece were disregarded. Two pairs of Euler angles were introduced to denote structure misalignment and error misalignment respectively, sets of reference frames were built up on the driving shaft, driven shaft and cross piece. Using direction cosine matrixes to describe the relation between different frames, then the expressions of components of the transmitted moment acting on the driven shaft were obtained via method of vector projection. Based on engineering fact, the transmitted moment model was simplified with respect to different misalignment conditions, such as only structure misalignment or only error misalignment is considered. Then for different misalignment situations, the lateral and torsional components of the transmitted moment acting on the driven shaft were simulated through numerical examples. It turns out that both the lateral moment and torque components will fluctuate based on the import torque, and that due to accelerating of the driving shaft, the fluctuation of transmitted moment will be more distinct, consequently, more complicated nonlinear dynamics behavior will arise.

“…Therefore, accurate prediction of effects of internal damping in composite material rotors is essential. So far, there have been less work related to the stability analysis, particularly effects of internal damping on the stability of a rotating composite shaft [4,[11][12][13][14]. Singh and Gupta [4,11] introduced discrete viscous damping coefficients to account for effect of internal damping.…”

“…Singh and Gupta [4,11] introduced discrete viscous damping coefficients to account for effect of internal damping. In a similar approach, dynamic instability analysis of composite shaft has been performed by Montagnier and Hochard [13], Mazzei and Scott [12], Kim et al [14]. In above cases, internal damping terms were included simply in equations of motion of rotating shaft, no internal damping modeling has been described.…”

The dynamical analysis of a rotating thin-walled composite shaft with internal damping is carried out analytically. The equations of motion are derived using the thin-walled composite beam theory and the principle of virtual work. The internal damping of shafts is introduced by adopting the multiscale damping analysis method. Galerkin’s method is used to discretize and solve the governing equations. Numerical study shows the effect of design parameters on the natural frequencies, critical rotating speeds, and instability thresholds of shafts.
