| 摘要:结合层次分析法（AHP）和质量功能展开法（QFD），构建磨片设计要求的质量屋（HOQ），经计算获得磨片设计要素重要度排序，从而可得到磨片设计的关键参数。通过专家打分法和实验验证，说明了QFD分析结果的正确性，由此可见QFD可用于盘磨机磨片设计关键参数的确定，可为适合国内纤维原料的新型磨片参数化设计提供科学依据。 |
| Abstract:In view of the fact that the segment of disc refiner used in paper industry is still imported or designed by manual experience currently, on the basis of Specific Edge Load (SEL), cut edge length per second (CEL) etc. theories and combining the methods of Quality Function Deployment (QFD) and Analytic Hierarchy Process (AHP), house of quality about segment design requirement was constructed, the importance degree ranking of segment design elements was achieved after calculation, and the key parameters of segment design were obtained. The validity of the QFD analysis results was confined by expert scoring method and experimental verification, so QFD could be used to determine the key parameters of disc refiner segment design, which provided a scientific basis for the parametric design of new disc refiner segment suitable for domestic fiber raw materials. |
