To solve the problem of lacking direct condition information in predicting equipment residual useful life(RUL),stochastic filtering model(SFM) is built for equipment's RUL prediction with indirect information,which is easy to get.SFM adopted Bayesian recursive theory which could fully use equipment's history condition information.For the estimation of model's parameters with insufficient samples,the Bayesian method is to update the parameters estimated by subjective data and objective information.Finally,th...

0引言基于状态的维修(Condition Based Maintenance,CBM),是一种新型的维修方式[1],主要指根据设备运行过程中所获得的实际状态信息决定维修时间,尽可能在故障发生前进行维修,能有效地防止维修不足和维修过剩现象,降低设备的运行费用,提高设备的可用度。一般来讲,采用直接状态?
