机织物结构相模型剖析和修正

针对机织物结构相传统模型未能敏感反映不同组织结构状态差异的问题，剖析了模型的约束条件和不足，建立了能够有效反映组织信息的结构相模型。提出了相对屈曲波高概念用于表征不同织纹组织中纱线的弯曲程度，为结构相模型的修正提供了理论参考。研究结果表明：结构相改进模型随屈曲波高的增加而增加，但呈非线性关系；对于不同织纹组织，形成等支持面的结构相是不固定的（0 结构相除外），相同屈曲波高对应着不同的结构相，三原组织的结构相值之间存在平纹＜ 斜纹＜ 缎纹；在低结构相区域，结构相与屈曲波高可看成非线性关系，在高结构相区域改进模型与传统模型有统一性。

Analysis and modification of structure phase model of woven fabric

Based on the conventional structure phase model of woven fabric fails to reflect the difference to different weaves, the constraints and the insufficiency of the model was analyzed, and the structure phase model capable of effective reflecting weave information was also established. It was the first time to put forward the concept of the relative yarn wave highness, which was used to identify the bending status of yarn in different weaves, providing theoretical basis for the modification of the structure phase model. The results show that the structure phase from the modified model increases with the increase of the yarn wave highness, but the relationship between them is nonlinear. For different weaves, the fabric structure phase is not fixed to form the equivalent support structure ( except for the phase 0 ) , and the same yarn wave highness corresponds to the different structure phases value with the order relationship as plain
