Peeling process development for thin flexible webs
(Oklahoma State University, 2007-06)
Many consumer products are manufactured from continuous media. When the media is thin and flexible, it is referred to as a web. Webs are typically manufactured by extrusion or casting; however, for some applications, a ...
Vibration of two axially translating media interconnected by Winkler elastic foundation
(Oklahoma State University, 2007-06)
Transverse vibrations of two translating strings interconnected by a Winkler elastic foundation, and subjected to axial loading are investigated. The natural frequencies are composed of two infinite sets, representing ...
Thermoelastic winding model with air entrainment
(Oklahoma State University, 2001-06)
Rolls of films are routinely stored under varying conditions before being unwound into downstream operations. During storage, interlayer pressures can change relative to the pressures generated during winding. These changes ...
Large deformation winding models
(Oklahoma State University, 2009-06)
Almost all winding models incorporate the assumption of small linear deformations and strain in development. As such these models treat the addition of a layer of web to a winding roll with linear analysis using linear ...
Free vibration analysis of thin, tensioned, helically wrapped webs using Mindlin-Reissner finite element method
(Oklahoma State University, 2007-06)
Free vibration analysis of a thin tensioned web, wrapped around a reverser was studied. The effect of helix angle was considered. The eigen-problem was formed using finite elements and solved numerically. Design parameters ...
Optimization by integrating engineering and business models
(Oklahoma State University, 2005-06)
To optimize is to find the "'best" solution given certain conditions and constraints. What is meant by best and how to find it has received scant attention. To the engineer, "best" may be fastest, strongest, most reliable ...
Shear slitting of aluminum webs using block knives
(Oklahoma State University, 2007-06)
C Shear slitting of two aluminum webs, namely 1050 H18 of 0.28 mm thick and 5182 H19 of 0.20 mm thick, using block knives are investigated through experiments using a laboratory slitter. This investigation focused on two ...
Robust control design using H-infinity methods in large scale web handling systems
(Oklahoma State University, 2003-06)
This paper presents H-infinity control strategies for elastic web transport systems. The aim is to reduce the coupling between web tension and web transport velocity. First of all, a multivariable H., centralized controller ...
Characterization of a slit edge using image analysis
(Oklahoma State University, 2003-06)
The paper deals with the characterization of edge quality of a slit web. The conventional way of determining the edge quality of a slit web is usually through visual inspection, sometimes under an optical microscope. In ...
Web line resonant frequencies
(Oklahoma State University, 2009-06)
The goal of this paper is to investigate the resonant frequencies of a system of idle rollers and web spans. Of particular interest is the determination of the minimum resonant frequency as a function of the number of idle ...
