主要研究了四步法 1× 1编织预制件的纱线编织结构。采用控制体积单元法和实验观察相结合的方法 ,根据携纱器的编织运动规律 ,将预制件分为三个区域 ,识别了局部单胞模型。在椭圆形横截面假设的基础上 ,考虑了编织纱线的填充因子 ,建立了编织工艺参数之间的关系。 Mainly studied the four-step method 1 × 1 braided yarn pre-woven structure. Using the combination of control volume element method and experimental observation, the preform is divided into three regions according to the weaving movement rule of the yarn feeder, and the local cell model is identified. Based on the assumption of elliptical cross-section, the filling factor of braided yarn was taken into account and the relationship between braiding process parameters was established.
