| 摘 要： | 采用分形几何的方法,计算实时采集的棉条厚度信号分维数,研究表明棉条厚度信号数据的盒维数与棉条不匀率单调正相关,一定窗口宽度的分维数均值与不匀率正相关,棉条厚度的时间序列数据的分维数序列与不匀率序列高度同步,因此可以用分维数评价棉条均匀度。

| Abstract: | The method of fractal geometry was used to calculate the fractal dimension of the cotton sliver thickness signal.The mumerical result indicated that the box dimension of signal data of the cotton sliver thickness is positively proportional to frequency of the irregularities of the sliver,and that the mean value of fractal dimension of widths of a certain window is propprtional to the irregularities of the cotton sliver,and that the sequence of fractal dimension of the time_series data of the cotton sliver thickness highly synchronizes with the sequence of the irregularities of the cotton sliver.Therefore the fractal dimension can be used to evaluate the evenness of the sliver. |
