摘　　要：铁谱定量分析是铁谱技术的主要内容之一,通过它获取的参数有助于工作人员对设备磨损磨损量的了解。通过建立铁谱定量的趋势分析可以直观的反映机械设备在运行过程中的磨粒浓度变化,便于工作人员分析设备的磨损状态和磨损趋势。时序分析方法是一门极为有用的统计分析方法,利用时序分析的方法建立DL随时间变化的模型进行预测研究,结果表明,该理论在DL的模拟及预测上具有较高的精确度,可以作为设备磨损预测的辅助手段。Ferrographic quantitative analysis is one of the main content of ferrography, through which to obtain the parameters that help staff to understand the wear quantity of equipment. Through establishing the trend of ferrographic quantitative analysis can be intuitive reflect the mechanical equipment in the running process of abrasive concentration changes, to facilitate the staff analysis of the wear state and wear trend of equipment. Time sequence analysis method is an extremely useful statistical analysis method, time sequence analysis method was used to predict the model DL change over time, the results showed that the simulation and prediction of this theory in DE, had high accuracy, could be used as the auxiliary equipment wear prediction method.
