Recently, the auxetic fabrics have gained much importance in the scientific and industrial community due to their excellent impact‐resistance property. Due to this property, they have several applications, including automotive, aerospace, and ballistic areas. The auxetic three‐dimensional (3D) woven fabrics are a less explored domain in the auxetic community. Herein, special attention is given to the numerical analysis of the 3D auxetic structure. The negative Poisson's ratio of 3D auxetic structures is studied using ANSYS workbench structural analysis module. The effect of binding yarn float length on negative Poisson's ratio is tested on ten different 3D orthogonal through the thickness structures with binding yarn float length of 1:1, 2:1, and 3:1. Furthermore, the effect of the number of binding yarns and the number of layers is also studied numerically. The results show that the auxeticity of the woven structure increases with increasing the number of binding yarns and their float length. Moreover, decreasing the number of layers from 3 to 1 increases the auxeticity.

3D辅助结构结合纱浮体长度的数值分析。
近年来，由于其优异的抗冲击性能，其在科学和工业界已变得越来越重要。由于这种特性，它们具有多种应用，包括汽车，航空航天和弹道领域。膨胀型三维（3D）机织织物是在膨胀型领域中探索较少的领域。在此，应特别注意3D膨胀结构的数值分析。使用ANSYS工作台结构分析模块研究了3D膨胀结构的负泊松比。在十个不同的3D正交结构的厚度结构上，测试了绑扎纱的浮线长度对负泊松比的影响，该厚度结构具有1：1、2：1和3：1的绑扎纱浮线长度。此外，还通过数值研究了固结纱数量和层数的影响。结果表明，机织结构的膨胀性随着绑结纱的数量及其漂浮长度的增加而增加。此外，将层数从3减少到1会增加吸引力。
