融合设备可用度和维修费用的起重机维修机会窗

Crane Maintenance Opportunity Window Integrating Equipment Availability and Maintenance Costs

对起重机的3种维修模式进行了描述,在此基础上将维修机会窗的概念引入起重机维修领域,提出了以最大设备可用度和最小维修费用为原则确定起重机维修机会窗的计算过程,并给出将这2个因素进行融合的计算步骤,最后以某桥式起重机大车车轮为对象进行了实例计算,验证了此方法的可行性。

This paper describes three maintenance modes of cranes,introduces the concept of maintenance opportunity window into the field of crane maintenance,proposes a calculation process for determining the maintenance opportunity window of cranes based on the principle of maximum equipment availability and the principle of minimum maintenance cost,and provides a calculation step for integrating these two factors.Finally,an example calculation is conducted for a wheel of overhead crane to verify the feasibility of this method.
