摘　　要：视情维修在提高装备的使用可用度、减少生命周期费用和提高维修保障效率等方面发挥了重要作用。在视情维修模式下,采用威布尔比例故障率模型描述了系统状态与故障率之间的关系,对伴随变量进行了相关性分析,以最大可用度为目标,建立视情维修的最优维修策略模型,并根据系统当前状态信息来判断装备是否已经达到最佳的维修时机。最后,对某型陀螺仪故障数据进行了实例分析,表明该方法在视情维修中的合理性和有效性。The Condition Based Maintenance plays a vital role in improving availability, reducing life cycle cost and improving maintenance support efficiency for equipment. Under this condition ,it describes the relationship between system states and the failure rate using weibull Proportional Hazard Model. Also, it analyzes the correlation of the covariates, and set up the maintenance model of optimal maintenance strategy for Condition Based Maintenance with the maximum availability as the goals. Then according to the information, it determines whether it is the best time to maintenance. Finally, taken one type of gyroscopes for example, its fault data is analyzed, which indicates the rationality and validity of this method in Condition Based Maintenance.
