| 摘 要： | 三维编织通过携纱器的间歇运动,使编织纱线彼此相互交织。编织纱线趋向于沿携纱器运动的方向运动。本文作者采用最小二乘法拟合携纱器的运动趋势线,系统地分析了编织过程中纱线的空间运动规律。在此基础上,获得的预制件结构单胞模型包含内部单胞和表面单胞。单胞的取向平行于预制件的表面,有利于材料的力学性能分析。

| Abstract: | In the braiding procedure, all of yarns are interwoven by the intermittent movement of carriers. The braiding yarn is tended to move along the direction of the carrier movement. In this paper, a method of least square approximation was introduced to predict the trend line of carrier movement. Then the yarn paths were analyzed systematically. Finally, two kinds of unit cells, the interior cell and the surface cell, were established. They are oriented in the same reference frame as the preform, which is quite suitable for the analysis of the mechanical properties. |
