The Research On Filament Winding Trajectory Of Non-Gyration

Filament winding technology based on gyration component is more and more mature , and the need of winding component in all fields is increasing, Study on filament winding molding movement track based on non- gyration component becomes the future direction of filament winding technology. There are two kinds of methods on research of filament winding , that is parametric winding with extensive application in the field of filament winding and mesh winding on which study has a late start relative to parametric winding, but the development of computer graphical processes mesh winding promising. Making blade which is a typical non- gyration component as subject investigated, this paper makes use of the winding methods to design the winding molding movement track of blade, and carries on contrast between parametric winding and mesh winding , in order to guiding the winding practice.In the aspect of blade's parametric winding , the paper expatiates on geodesic steady winding theory and non-geodesic steady winding theory of parametric winding, and presents non-slip and non-bridge qualification of non-geodesic winding. Based on them, parametric equations are obtained by predigesting configuration of the blade to establish blade's math model, geodesic differential equation and non-geodesic differential equation of blade's trunk are founded, and according to these equations winding line type is designed. In the process of end plate's line type design, we use the way of trunk's line type design for reference. In the aspect of blade's mesh winding, the theories of mesh winding and implementation process are expatiated, also the paper obtains non-slip and non-bridge qualification from the angle of geometry. Afterwards, the blade's winding tracks are designed again by mesh winding. First of all, meshing the blade's model which is predigested ahead and picking up information of mesh nodes. Then, sorting mesh notes and designing arithmetic of doffing points'judgement to judge whether the mesh notes are doffing points. Finally, obtaining winding line type. During design line type by the two methods, emulator based on Visual C++ and OpenGL is used to validate winding line type instantly. After obtaining winding line type, postposition processes are implemented to compute...
