一种新型大张力纤维缠绕控制系统的研制

简述了大张力控制的总体方案,提出了一种以磁粉制动器为执行元件,用张力传感器作为对纤维丝束进行张力实时检测的反馈元件,运用张力分配方案对张力进行调整的闭环控制系统,建立了张力控制的数学模型,搭建了软件实验平台。基于该平台,分别进行了恒张力、大张力阶跃的实验研究。实验结果表明,所设计的张力控制系统响应速度快,张力波动小,满足纤维缠绕大张力控制的要求。

Development of a New High Tension Fiber Winding Control System

The general scheme of high tension control system is introduced .A fiber high winding tension control system was de-signed, with a set of the magnetic powder brake as the actuator , with tension sensor of fiber ribbon tension real-time monitoring as feedback element , and setting the tension control allocation scheme to adjust the tension of a closed-loop control system .The mathe-matical model was established , while the way to design hardware and software platform of the tension control system .Study works on constant tension , tension step response were carried out separately base on the proposed platform .Experimental results show that the proposed tension control system responses fast and the tension fluctuation rate is low , which can satisfy the requirements of the high tension control for fiber winding .
