摘要/Abstract

摘要： 通过对现场采集的226条数控车床维修时间数据的分析,建立了其维修时间的分布模型,CNC车床维修时间服从对数正态分布,从而得出了其维修性特征函数(维修度函数M(t)、概率密度函数m(t)、维修率函数μ(t))。在此基础上对CNC车床的维修性水平进行了评价。

关键词: CNC车床, 维修性, 对数正态分布

Abstract: After analyzing 226 datas of repairing time collected in field,the distribution model of repairing time of CNC lathes was established.The maintainability functions,including maintainability degree M(t),probability density m(t) and maintainability rate μ(t),were given.The repairing time fits lognormal distribution.From the distribution,the maintainability level of CNC lathes has been evaluated.

Key words: CNC lathes, maintainability, lognormal distribution
