摘　　要：为提高簇绒地毯分辨率,提升地毯的品质,建立正确的纱线张力模型是精确控制地毯绒高的关键。首先介绍了簇绒装备系统的组成及纱线的导向路径,然后将米纳科夫的拓展欧拉公式引入纱线张力系统,考虑纱线束为黏弹性负载,分阶段对张力系统进行建模。其中,纱线张力系统模型包括提花罗拉、恒张力导纱罗拉和多层导纱器。通过对比仿真与实验所得的纱线张力变化曲线,验证了模型的准确性,为下一步张力控制器的设计提供了参考。In order to improve the resolution of tufted carpet and enhance its quality,constructing a proper yarn tension model is the key to accurately control the pile height of tufted carpet.This paper firstly introduced the components of a carpet tufting machine and the path of yarns.Then,Euler formula derived from А.П.МИНаКОВ′ is introduced into yarn tension system.Considering yarn bundle as viscoelastic load,sectional modeling for the yarn tension system is undertaken,including models of jacquard roller,constant tension guide yarn roller,and multi-layer yarn guides.Finally,the correctness of the models is verified by comparing the simulated yarn tension curves with those achieved by experimental methods.This research provides a reference for further work in designing yarn tension controllers.
