基于RCM的冶金单体设备预防性维修模型

摘要

应用以可靠性为中心的维修(RCM)方法对冶金单体设备的维修策略进行研究.以开卷机为具体对象,引入役龄回退因子对设备役龄进行修正,采用威布尔分布对设备的故障间隔时间进行拟合,得到设备的故障率函数,并以设备维修总成本最小化为目标,建立基于可靠性和经济性约束的不完全预防性维修模型.通过一个算例对该模型进行了验证.%Metallurgical equipment maintenance strategy was researched by adopting the reliability centered maintenance (RCM) method. Age reduction factors were introduced to revise the service age of the decoiler. Weibull distribution was used to fit the failure interval of the equipment with the failure function obtained. To minimize the maintenance cost, a preventive maintenance model for the single metallurgical equipment was established. And the model was validated with an example.
