摘要: 机械装备一般都是可维修设备。采取积极有效的预防性维修,合理安排预防性维修活动,对于减少装备的故障次数及提高使用率具有重要的现实意义。以在有限使用时间区间内工作的机械装备为研究对象,分别从维护成本及综合考虑维护成本和可靠性两个方面建立了预防性维修优化模型,并利用非线性优化软件对其进行了求解,确定机械装备在有限工作时间区间内最优的预防性维修次数以及预防性维修周期。算例表明,所提出的预测预防性维修次数和周期的方法是可行的,可为机械装备制定预防性维修大纲、预测机械装备使用寿命提供参考。

Abstract: Mechanical devices are repairable. Taking an effective preventive maintenance and reasonably arranging the preventive maintenance activities are very important to decrease the failure frequency and improve the utilization ratio. The mechanical device working in finite time horizon is studied. Maintenance cost and comprehensive consideration of maintenance cost and reliability are modeled, a nonlinear optimization software is used to solve the optimization model, and the optimal times and cycles of preventive maintenance in finite time horizon are determined. The examples show that the method of forecasting the preventive maintenance frequency and cycle is feasible. This optimization policy model can provide references for making the preventive maintenance program and predicting the service life of mechanical devices.

Key words: ordnance science and technology, preventive maintenance, maintenance strategy, optimization
