摘要
数控机床是装备制造业的工作母机,是国家综合国力的象征,其可靠性已成为制约行业发展的瓶颈。数控机床可靠性建模是可靠性工程的基础,主要对数控机床可靠性建模方法和技术的研究进展进行综合评述。可靠性建模方法主要分为基于故障时间数据的可靠性建模方法、基于多源层次信息集的可靠性建模方法、基于性能退化数据的可靠性建模方法、基于动态特性参数的工艺可靠性建模方法四种,分析了各类可靠性建模方法的研究历程和技术进展。在数控机床可靠性建模方法取得明显进展的基础上,指出现有可靠性建模方法存在的不足,然后对数控机床可靠性建模方法研究的动态和热点进行论述。最后,从可靠性建模方法的发展规律、技术应用以及行业需求的角度对数控机床可靠性建模方法和技术的发展趋势进行展望。
CNC machine tools play an important role in the equipment manufacturing industry,and their reliability level has become the bottleneck restricting the development of the industry.Reliability modeling of NC machine tools is the basis of reliability engineering.A comprehensive review on the state of the reliability modeling technology research is given.Reliability models are mainly divided into four categories:reliability modeling method based on fault time data,reliability modeling method based on multi-source hierarchical information set,reliability modeling method based on performance degradation data and process reliability modeling method based on dynamic characteristic parameters.The research process and technical progress of various modeling methods are analyzed.On the basis of affirming the obvious progress made in the reliability modeling method and technology of CNC machine tools,this paper analyzes and points out the existing problems and shortcomings of the research work,and discusses the trends and hotspots of the reliability modeling research of CNC machine tools.Finally,the development trend of reliability modeling methods and technology of CNC machine tools is prospected from the perspective of reliability modeling development law、engineering application and industry demand.
