【摘要】：针对设备隐性故障预防性维修策略的问题,通过比例役龄消减模型建立"翻修期"的设备隐性故障维修模型。在假设针对隐性故障的检查维修是非理想的,而在"翻修期"翻修是理想的基础上,建立了隐性故障预防性维修策略的优化模型。该模型包含了可靠度约束模型和成本率函数模型,并进行了数值模拟。模拟案列表明:非理想维修效果会降低隐性故障可靠性水平;当检查维修接近于理想时,存在最优检查周期使得成本率函数最小,当役龄回退因子减小足够多时,该检查周期不存在。
[Abstract]:In order to solve the problem of preventive maintenance strategy of hidden fault of equipment, a maintenance model of hidden fault of equipment in "renovation period" is established through proportional service age reduction model. It is assumed that the checking and maintenance of hidden fault is not ideal. On the basis of the ideal renovation period, the optimization model of hidden fault preventive maintenance strategy is established, which includes reliability constraint model and cost rate function model. The numerical simulation shows that the non-ideal maintenance effect will reduce the hidden fault reliability level; When the inspection maintenance is close to ideal, the cost rate function is minimized by the existence of an optimal check period. When the service age regression factor is reduced enough, the inspection period does not exist.

【正文快照】： 设备维修经历了从事后维修、预防性维修到状态监控三大发展阶段,预防性维修由于具有减少设备故障频率、提高设备可用性和降低维修成本方面的优点,至今在设备维修中占据着最重要的地位[1]。Barlow等[2]开创性地提出了“最小维修”的概念,为预防性维修模型的发展奠定了基础。随
