| 摘 要： | 机械故障预测中,反映系统变化的特征参数往往含有多种趋势成分.引入组合预测模型,用灰色模型描述机械故障发展中的确定性趋势,用AR时间序列模型描述机械故障中的随机趋势.实践证明,较单一模型具有更高的预测精度.

| Abstract: | For fault prediction,there are always various trends in machinery fault development.Since AR model is suitable for describing the stationary random process and grey model is good at forecast the defined trends,it is appropriate to build combined forecast models using the above-mentioned models.In this paper,so higher accuracy could be achieved by performing the fault quantification in terms of combined forcast model. |
