| 摘 要： | 首先应用故障总时间法对某型号数控机床在一年中的25个随机截尾故障数据进行预处理,然后采用图示和统计两种方法对故障数据进行趋势检验,最后通过参数估计和线性相关检验确定了数控机床故障过程符合威布尔过程。研究结果为数控机床的可靠性分析和评价提供了理论依据。

| Abstract: | The 25 failure data with random ending from a numerical control(NC) machine tool in one year were pre-processed with total failure time method,then the tendency test was performed for the failure data by the graphic method and the statistic method.It was found that the failure process of the NC machine tool conforms to Weibull process model by means of the parameter estimation and the linear relativity hypothesis test.A brief analysis was made to provide a theoretical basis for the reliability analysis and evaluation of the NC machine tools. |
