基于模糊综合评判的机械零件材料选择方法

针对在选择机械零件材料时采用传统方法所具有的主观性缺陷,本文结合设计实例,运用模糊数学理论,建立了零件材料选择的模糊综合评判的数学模型,能从多种可用材料中较客观、合理地确定出最适用的一种材料,从而提高了设计质量.

A Method of Choosing Materials for Mechanical Parts Based on Fussy Synthetic Judge

In view of the subjective defect of using traditional method to choose materials of mechanical parts, this paper set up mathematical model for fuzzy synthetic judge, combinning with an example of a practical design, applying fuzzy mathematical theory. The model could objectively and reasonably select the best material from many usable ones, so design quality might be improved.
