基于模糊灰色信息集成理论的磨粒识别研究

Fuzzy-grey Theory in the Application of Wear Recognition

根据灰色系统理论和模糊数学,引进了一种灰关联度综合评价模型和模糊相对权重的概念,并将两者相结合运用到铁谱分析的磨粒识别中,提出了一种新的基于模糊灰关联度的磨粒识别方法。计算表明,该方法比单一地使用灰色关联、模糊聚类具有更好的准确度与稳定性。

Based on the grey theory and the fuzzy theory, the grey relationship degree evaluation model and the fuzzy relative weight （FRW） were introduced. By combining them, a new concept of fuzzy grey relation grade （FGRD） was proposed. A new method of wear recognition was introduced by using the new concept. It is proved that the result of the new method is more accurate and stable than that of only using the GRD or fuzzy clustering.
