“…Kafi and Hosseini [15] studied nonlinear axial‐flexural‐flexural‐torsional non‐stationary dynamics of a nonlinear shaft passing through critical speed using an asymptotic method. They stated that the lamination angle has a main effect on the response of the shaft in resonance and post‐resonance regions.…”

In this study, a set of generalized nonlinear equations of motion for Timoshenko composite shafts is derived using the geometrically exact approach. These partial differential equations of motion are discretized by Galerkin method and the free vibration of an orthotropic spinning shaft with hinged‐hinged boundary conditions is investigated using the multiple‐scale method. We find that in the case of two mode discretization, composite couplings can have significant linear and nonlinear effects on the behavior of the shaft and that these effects were not predictable in the classical model. Also, in the investigating of composite layering we find that the effects of the fibers angle as well as the composite couplings can be noticeable, and these effects are greater in the case of the asymmetrical layering.

Vibration control is the key to development of high-speed and light-weight transmission system. There are many factors affecting the vibration, and the influence of misalignment is the most obvious. Therefore, it is important to understand the dynamic response of transmission shaft with misalignment. In previous studies, researchers studied the influence of plane angle misalignment. However, there are few researches on the effect of spatial misalignment on shafting vibration. In this paper, a numerical model of shafting with spatial misalignment is established. The influence of plane angle misalignment and spatial angle misalignment on the vibration is studied. The numerical and experimental results show that the vibration of shafting with spatial angle misalignment is bending-torsional coupled vibration, and the two kinds of vibration reinforce each other, and the torsional vibration is the main vibration. Compared with the influence of plane angle misalignment, the influence of spatial angle misalignment is more obvious..
