Abstract

The invention discloses a building method for taper-changeable composite fiber winding adhesive layer models. The building method for the taper-changeable composite fiber winding adhesive layer models is a new method for building three-dimensional solid models of composite fiber winding adhesive layers in virtual three-dimensional environments by a modularized program drive method; according to a winding process of composite fiber winding products, three-dimensional space coordinate parameters of positioning control points on the fiber winding adhesive layers are calculated according to a normalized curvilinear equation, and modeling is realized by combining a three-dimensional design environment characteristic operation method; the problems of coordinate shifting of the positioning control points of the adhesive layers and segmental splicing of space curves both caused at spring layer / striding ring positions by composite fibers during simulation of the composite fiber winding adhesive layers are solved. The building method can build the composite fiber winding adhesive layer models with any filament winding lengths, and the models have high similarity to actual composite fiber winding adhesive layer products; the three-dimensional composite fiber winding adhesive layer models have wide range of adaptability to taper of winding mandrel bodies and high dimensional accuracy.

Description

technical field [0001] The invention belongs to the technical field of computer graphics and three-dimensional solid modeling, and in particular relates to a method for establishing a compound fiber winding variable taper adhesive layer model. Background technique [0002] Composite fiber winding molding is to impregnate the continuous fiber with resin glue, under the action of fixed tension, wind it on the mandrel according to the predetermined relative motion law, and form a fiber winding product with a specific shape after curing and molding. Common composite filament winding products are generally cylindrical or conical with an axisymmetric shape. The common manufacturing method is to wind the fiber on the mandrel according to the trajectory of the helix. The law of motion is that the mandrel rotates at a constant speed around its central axis, and the winding head moves back and forth along the axis of the mandrel at a specific speed, thereby realizing spiral winding o...
