Pullout theory is very important in improving efficiency, quality, and production costs. Because production efficiency is too low for mechanical drafting equipment, a simple multi-field coupling model of fiber mechanics based on conserving momentum is proposed that considers the distribution of the fiber speed point, slip rate, and friction mechanics. When the roller draft multiple is increased, the position near the rear roller clamp mouth in the draft area will show a sharp decrease of fiber, which is caused by the rapid movement of the front fiber to drive the floating fiber movement, and it is also the existence of the fiber change point. When the roller spacing increases, the draft efficiency decreases, although the pressure applied by the roller to the fibrous strip has a weak effect on the draft efficiency. This research increases our understanding of drawing and provides theoretical support for the design of a new type of drawing.

基于多场耦合的萝拉牵伸纤维根数预测

拉拔理论对于提高效率、质量和生产成本非常重要。针对机械牵伸设备生产效率太低的问题,提出了一种考虑纤维速度点、滑移率和摩擦力学分布的基于动量守恒的简单纤维力学多场耦合模型。当罗拉牵伸倍数增加时,牵伸区靠近后罗拉夹嘴的位置会出现纤维的急剧减少,这是由于前纤维快速运动带动浮纤运动造成的,也是纤维变化点的存在。当罗拉间距增大时,牵伸效率降低,但罗拉对纤维带施加的压力对牵伸效率的影响较弱。
