【 摘 要 】

A new FE modeling system for braided tube has been proposed. The input data are the shape of section of a braid, the braided angle, and the number of layers and the diameter of tube. The generated model has been verified by comparison with the experimental results and numerical ones. The mechanical properties for the tube have been analysed by the generated model and FEM code. On the other hand, the rigidity and the strength for the tube have been measured by three point bending and torsion tests. The experimental results have agreed with the numerical results. The agreement has encouraged that the proposed procedure can be applied to generate FE models for braided tubes with complex geometry.
