Lagrangian modeling and analysis of the dynamics of frictional winding mechanisms
2011
This paper investigates the dynamics of frictional-type winding mechanisms widely used in textile industry. The mechanism under study is used to wind various kinds of thread onto bobbins of cylindrical form. The system essentially consists of a motor-driven cylinder which is pressed to a cylindrical bobbin hence bringing the latter into rotation through friction between the two surfaces. A textile thread is supplied into the contact zone and winds around the bobbin. For the winding operation to proceed accurately, the winding mechanism must be free of vibrations to ensure a constant and reliable contact zone.
