摘 要 为了分析锯齿轧花过程中籽棉的受力状况，以期提高皮棉质量，在已有的层合板棉朵模型和三维编织棉朵模型的基础上，提出了一种新的棉朵模型：含棉籽的棉朵模型。该模型考虑了实际棉朵中棉籽的存在，棉纤维束按照一定的规律排列成立体网状的结构，假设纤维束具有圆形截面，截面形状沿轴向保持不变。在该模型的基础上利用ANSYS Workbench对轧花过程进行了模拟，分析了不同锯齿转速和棉籽密度对轧花过程的影响，结果得出锯齿转速越大，棉纤维受影响越剧烈，但转速过大也会损伤棉纤维，棉籽密度在580kg/m3时锯齿轧花效果最明显。且实验值与理论值误差较小，说明了模型的合理性。

Abstract： In order to analyze the stress state of seed cotton in sawtooth rolling process and improve the quality of lint cotton, a new model of cotton seed is proposed in this paper, which is based on the existing model of laminated board and three-dimensional woven cotton seed. The model takes into account the existence of cotton seeds in actual cotton. The cotton fiber bundles are arranged into a three-dimensional network structure according to a certain rule. The fiber bundles have a circular cross section, whose shape remains unchanged along the axis. On the basis of the model, ANSYS Workbench was used to simulate the ginning process, and the influence of different sawtooth speed and cottonseed density on the ginning process was analyzed. It can be seen from the results that the greater the sawtooth speed is, the more severe the impact of the cotton fiber is, but the larger the speed is, the cotton fiber will be damaged. The effect of sawtooth ginning was most obvious when the cotton seed density was 580kg/m3. The error between the experimental value and the theoretical value is small, which shows the rationality of the model.
