数控车床的故障间隔时间分布模型与拟合检验

Failure Interval Distributed Model and Fitting Test of CNC Lathes

针对某系列数控车床的故障间隔时间分布模型进行了参数估计和假设检验,得出了服从威布尔分布的结论。确定了该系列数控车床的可靠性特征量。得到了相应的拟合曲线。

Parameter estimation and hypothesis testing methods were used to analyse MTBF model of a certain serial CNC lathes. The resuh shows that MTBF model submits to Weibull Distribution. Reliable eigenfunctions of this serial CNC lathes were concluded. Fitting curves were got.
