摘  要:
在分析加工中心典型故障模式时,同时考虑故障发生的随机性和模糊性,将故障间隔时间定义为一个随机模糊变量,建立随机模糊条件下的加工中心故障模式发生机会模型。使用随机模糊模拟技术,计算出典型故障模式发生机会并对典型故障模式进行排序,通过典型故障模式发生机会和发生频率的对比分析,从整体上掌握了此型号加工中心故障的发生情况,找出了对加工中心可靠性影响较大的故障模式。

摘  要:
In the analysis of the typical failure mode,randomness and fuzziness were taken into consideration,time between failures was defined as a random fuzzy variable,then the occurrence chance model was built.Random fuzzy method was used to calculate the occurrence chances of typical failure modes and the ranking.By virtue of the analysis of the occurrence chances and occurrence frequencies,some important conclusions could be made out.The failure mode which influenced the machining center most could be found out,the conclusions provided useful basis on how to eliminate these failure models and how to improve the reliability of machining center of this type.
