Modeling and identification of the source of oscillations in web tension
(Oklahoma State University, 2009-06)
Although there has been much work in dynamic modeling of different web handling elements and web longitudinal behavior, efforts to systematically validate models by experimentation on a web platform are non-existent. ...
Computation of span length variations due to out-of-round material rolls
(Oklahoma State University, 2009-06)
It is well known that non-ideal elements such as out-of-round/eccentric material rolls affect web tension. However, the mechanism through which these non-ideal components induce tension oscillations was not clear previously. ...
Web tension behavior in the presence of eccentric rollers: Modeling and validation
(Oklahoma State University, 2011-06)
Since rotating machinery is used to transport the web on rollers, it is common to observe periodic oscillations in measured signals such as web tension and web transport speed. These periodic oscillations are more prevalent ...
