基于质点模型的横编织物结构研究与计算机模拟

为分析线圈类型对织物形态的影响,在STOLL公司生产的3.5.2机号的HP530型电脑横机上编织一系列成圈、浮线、集圈和移圈结构单元组合的织物,利用超景深显微镜拍摄并测量线圈结构参数,总结出不同结构对织物形态的影响规律。从力学角度研究织物线圈变形的根本原因得出,由于织物中线圈类型的改变,打破原有的受力平衡,造成纱线张力的改变,在张力作用下纱线在相邻线圈之间发生转移,从而导致织物形态改变。将织物中的线圈简化为质点,线圈的变形规律被转化为质点系统的位移规律,该研究为利用质点系统进行横编织物的计算机模拟仿真提供理论研究基础。

Research of flat knitted structure and compute simulation based on particle model

To analyze the impact of loop style on fabric appearance, those looping, floating, tuck and transfer unit structure fabric were made by STOLL HP 530 computerized flat knitting machine (E3.5.2). The photograph of those structure taken by the depth of field microscope, and those loop structure parameter were measured. The influence law of different loop style on fabric appearance is summarized. The root cause of the fabric deformation was analyzed from the point of mechanics, It was found that due to the change of loop style in fabric, the original force equilibrium is broken, cause the yarn tension. Under the action of yarn tension, yarn transfer between the adjacent loop, led to the fabric appearance change eventually. The loop in the fabric was simplified as a particle, the deformation law of loop is converted to the displacement law of particle system. This research provide theoretical research foundation for the flat knitting fabric computer simulation using particle system.
