Abstract: Complex fiber is wound on the spindle that is the main production of the composite fiber winding package. During the winding production, the uneven tension, axial movement and the internal thermal stress are the defect resources. It needs to simulate the winding package that the shape size and the internal thermal stress can be calculated. For the winding production simulation, provided the program driven method based on the cylindrical curve equation and computer three dimension (3D) graphics transformation to calculate the coordinates of structure point quickly. And then, in the 3D design environment the center line of winding model is built. The center line is used to build the winding model by the modeling operation. Meanwhile, the problems such as the coordinate optimization of construct point, the curve segments splice and the automation assembly are solved. These problems are caused by the reason that the fibers are moved from the winding layer to the next layer or across the winding circle. The experimental results show that the method can be applied to the generation of the adhesive layer defect model for any length with multiple defects and the accumulative axial error of a single layer is no more than 1.5 times of the fiber diameter.
