运用数理统计的有关原理和方法 ,通过构造磨屑群简化并规范了量化铁谱定性分析的过程 .在磨屑群体特征分析的基础上 ,应用模糊数学的有关原理和方法 ,通过构造磨屑群体特征参量 ,推导出各因素和各因素集的隶属函数 ,结合铁谱工况监测的经验 ,建立了铁谱分析模糊综合评判系统 ,并通过现场工况监测实例 ,检验了该系统分析结果的可靠性 Based on the principles and methods of mathematical statistics, the process of qualitative analysis of quantitative ferrographs is simplified and normalized by constructing wear debris group.Based on the analysis of the characteristics of wear debris population, the author applies the relevant principles and methods of fuzzy mathematics, The membership function of each factor and each factor set is deduced. Combined with the experience of iron condition monitoring, a fuzzy comprehensive evaluation system for ferrographic spectrum analysis is established, and the example of field condition monitoring is used to verify the reliability of the system analysis results Sex
