专用计算机数控机床故障率实验研究

The Failure Rate Experimental Study of Special CNC Machine Tool

基于单样本的专用数控机床 ,通过对故障数据的实验分析 ,确定了单样本专用数控机床故障分布函数和故障率函数 ,依据故障率函数可以判断专用数控机床此时是处于早期故障期还是偶然故障期 ,进而采取措施消除故障 。

Based on one-sample special CNC machine tool, the failure distribution function and failure rate function, whose failure data have been analyzed by experiment, are determined in this paper. The special CNC machine tool time of which are in early failure or haphazard failure can be judged in terms of the failure rate function of it, and that the reliability of special CNC machine tool is improved by eliminating failures.
