Filament Winding of Conical Structures with Elliptic Cross Section

摘要

This paper presents a software, ELLIPSE-COMP-2009, for the simulation and the control of ellipsoidal mandrels winding in the manufacturing of composite structures. The winding machine is controlled by a numerical-control unit. The deposit point of the fibre on the mandrel follows the geodesic lines to optimise the consumption of the ribbon and avoid fibres sliding over the mandrel. In this paper, we determine the geodesic line over ellipsoidal structures, subsequently the coordinates of the feed-eye in the space; leading to stabilise the fibre setting by synchronizing the mandrel rotation and the feed-eye displacement. The case in which the cross section of the ellipsoidal structure remain constant has been studied and published as ELLIPS-COMP-2002 /I/, case of winding right beams with elliptical cross section. ELLIPSE-COMP-2009 presented on this paper is an extension of ELLIPSE-COMP-2002 to the winding of conical beam with elliptical cross section.
