Parametric Vibrations of Axially Moving Materials--a Review

This paper provides a comprehensive review of the state of art for parametric vibration of axially moving materials in the past two decades, with particular regard to the subjects of the parametric vibration behavior and stability of axially moving media with time-varying tension and axially translating velocity. The paper discusses firstly the governing equations. Then some of important problems such as solution methods and problems studied are explained. In the following two sections, we review respectively in detail the recent research progresses for the vibrations of axially moving stirng and beam systems with time-varying translating velocity and tension, in which the type of models, the forms of time-varying translating velocity and tension, the solution methods employed in the investigations and the vibration behaviors (vibration response, natural frequencies, dynamic stability etc.) of these systems are discussed in detail and deeply. At last the paper concludes with a discussion of several issues for future research in this field.
