物元可拓识别模型在发动机润滑油性能评价中的应用

Application of matter element extension recognition model to evaluating the engine lubricant performances

基于可拓集合变换与相关函数分析法,结合发动机润滑油性能指标等级的经典域物元与节域物元,建立发动机润滑油性能指标等级的物元可拓识别模型,并进行实证分析.结果表明:物元可拓识别结果与属性识别模型的判别结果具有较好的一致性,对发动机按质换油具有一定的参考意义.

The matter element extension recognition model for engine lubricant performance rank is established, by using the extensics theory and method, the classical field matter elements and segment field matter elements are put forward on the basis of transformation extensive set and analysis of correlation function. The example verification results show that the methodology is coherent with the results of attribute recognition method, the matter element extension recognition method provides for the lubricant changing by the quality.
