이송중인 웹과 롤러의 슬립에 관한 연구

다국어 초록 (Multilingual Abstract)

Air entrainment can become a significant problem in a web handling process. The development of air film<br/>
between a web and an idle roller can cause a reduction of traction and traction coefficient, by which a slip is<br/>
occurrred. Computational and experimental study was carried out to describe the slippage of an idle roller for<br/>
given operating conditions, tension and web velocity. An extended mathematical model to find out a slip<br/>
condition was developed by using the models of air film height, dynamic traction coefficient, and torque<br/>
balance of a rotational roller. And by using the extended model, a mechanism to define the slippage between<br/>
the roller and the moving web was suggested. The results of simulation and experiment showed that the<br/>
extended dynamic model could properly characterize the rotational motion of the idle roller by considering<br/>
dynamic traction coefficient. By examining the rotational motion of the idle roller with web dynamics(speed),<br/>
the mechanism to define al slip condition between the roller and the web was found to be effective.
