摘要
使用概率密度函数的基本原理,对3个纤维长度根数分布密度函数(精梳机输入小卷根数分布和落棉与精梳条的纤维长度根数分布)进行比较,导出纤维长度根数分布在梳理过程中的变化规律。讨论输入和输出纤维长度根数分布应该满足的条件。利用求解线性方程组的方法计算并得到精梳机梳棉效能的表征曲线。结果表明,利用纤维的长度根数分布计算方法能够较好地对精梳机工作效能进行细致的评价。进一步探讨纤维在梳理过程中发生断裂的表征方法,提出一种能够反映纤维在梳理中断裂程度的指示量。利用这些结论可以对精梳机加工过程进行优化并估计纤维在加工中的断裂情况,为精梳工艺设计提供重要的依据。
Using the basic principle of probabilistic density functions, three cotton fiber length distributions by number （including one input and the two outputs cotton fibers） are compared, deducing the changing rule of the fiber length distribution during combing. The conditions under which fiber length distributions at both input and output should be met is discussed. The characterization curve of combing effectiveness of the combing machine is obtained by computation using solving linear equations. The work has shown that the computation method based on fiber length distributions can effectively evaluate the working efficiency of the combing machine. Furthermore, a reasonable indicator is given so that the fiber breakage during combing can be characterized. The findings can be used in optimizing the combing process and estimating the fiber breakage during combing and as a reference for the design of combers.
