模糊数学在CNC系统可靠性指标评估中的应用

The application of blurry mathematics in evaluation of reliability indicators of CNC system

模糊数学法是采用模糊数学建立模型,对指标进行综合评价的方法。CNC系统是数控机床的重要组成部分,在可靠性研究过程中,该系统故障数据较少且受多种因素影响。为了更精确地评估其可靠性指标,本文将模糊数学理论较好地运用到CNC系统,从而建立了一个可靠性指标的模糊评估模型。

The method of blurry mathematics is a method which adopt blurry mathematics to construct model and implement comprehensive evaluation to indicators.The CNC system is important composition of CNC machine tool,and the system has little malfunction data as well as influencing by many factors in the research process of reliability.In order to eveluating the reliability indicators more exactly,the theory of blurry mathematics is applied to CNC system properly,and consequently,the blurry evaluation model of reliability indicators is established in the paper.
