模糊理论在发动机油性能评价中的应用

摘要

以4种发动机油为研究对象,提出了一种基于油液监测技术,结合层次分析法和模糊数学法的模糊综合评价方法。分析确定了发动机油性能的评价因子和评价指标权重,利用模糊综合评价法对润滑油的性能进行了综合评价。计算结果表明：该评价方法与实际情况相符合,可信程度较高。%Fuzzy comprehensive evaluation method combined analytical hierarchical process and fuzzy mathematics was put forward based on oil monitoring technology and four engine oils.The weigh set and the fuzzy functions were determined for engine evaluation factors of performance.,Oil performance was evaluated by means of the fuzzy comprehensive evaluation method.The results show that the analytical method is corrlerated with actal and its reliability is high.
