Abstract:

The motion law of four-step braiding technique is summarized.Through cubic Bspline curve fitting,the fitting coordinates can be got from the spatial coordinates.The algorithm that can achieve the static model of yarn entity is designed.Based on the fitting coordinates,the yarn space grid coordinates and the static model of the yarn entity are obtained.The dynamic display of the yarn trajectory and the yarn entity generation process is achieved.The GUI interface is designed and the program that can be independent from the Matlab environment is compiled.

Key words: 3-D braiding;static model;dynamic simulation;graphical user interface (GUI)
