摘要：

为分析棉纤维集合体在压缩过程中纤维受力情况来提高棉花压缩打包的质量,结合三维编织复合材料的细观几何建模思想,将具有相同圆形截面的棉纤维束按照三维四向编织复合材料的纤维分布进行排列,构建新的棉纤维集合体模型。将该模型应用于棉纤维集合体压缩过程分析,研究了棉纤维集合体压应力与相对密度的变化关系及棉纤维应力变化情况,分析了回潮率对棉纤维集合体压应力的影响。结果表明:随回潮率的升高,棉纤维集合体应力呈现先降低后升高的趋势,当回潮率位于8.8%~12.3%之间时,棉纤维应力最小;仿真结果与试验结果相符,说明该棉纤维集合体模型具有合理性。

Abstract:

In order to analyze the stress of cotton fiber assembly in compression and improve the quality of cotton bales, a new model for three-dimensional braided composites is established. In this model, cotton fiber bundles were assumed to have the same circular cross-section and arranged according to the three-cell structure of three-dimensional four-direction braided composites. The model was subjected to compression analysis assuming a cotton fiber assembly, and the relationship between compressive stress and relative density was analyzed with the variation of cotton fiber stress. In addition, the influence of moisture regain on the compressive stress of cotton fiber assembly was analyzed. The results show that the stress of cotton fiber assembly decreases first and then increases as the moisture regain is increased. When the moisture regain is between 8.8% and 12.3%, the stress of cotton fiber is the minimum. The finite element analysis results are consistent with the experimental results, demonstrating the validity of the model.

Key words: cotton fiber assembly, finite element model, compression, moisture regain, stress, cotton bales
