碳纤维经纱织造损伤状态评价标准及实现方法

为使上位控制系统能够实时监测碳纤维经纱织造的损伤状态,进而为调整织机运行速度,改变纱线张力,甚至停机检查等控制提供重要参考数据,提出了一套适用于碳纤维经纱织造损伤状态的评价标准和实现方法。采用模糊控制理论,分析和选择了模糊算法的输入量和输出量,根据单项指标的影响权重制定出模糊规则,运用Mat Lab模糊逻辑工具箱,编程实现了对单根经纱总体损伤程度的评价。通过Labview软件平台调用Mat Lab程序,实现了区域多根经纱总体损伤程度的评价。评价算法损伤评价结果与人工经验判断结果误差小,评价标准和实现方法具有可行性。

Evaluation standards and program implementation on damage status of carbon fiber warp weaving

In order to online monitor damage status of carbon fiber during weaving with upper control system for further providing important references to adjust the loom speed and change the yarn tension and even check stands, a set of applicable evaluation standard and implementation method on damage status of carbon fiber during weaving were put forward. According to the fuzzy control theory, the input and the output of the fuzzy algorithm were analyzed and fuzzy rules were also put forward. The realized program can provide evaluation of single yarn damage degree with the MatLab fuzzy logic toolbox. By calling Matlab procedure the evaluation of regional yarn damage degree is implemented on Labview software platform. The error of damage evaluation results between evaluation algorithm and artificial experience judgment is small. The evaluation standard and implementation method are feasible.
