摘　　要：以齿轮箱摩擦学系统为研究对象,通过分析齿轮摩擦学与动力学信息之间存在的异同性,建立了齿轮摩擦学与动力学信息故障诊断相关性分析模型。对模型中两类不同量纲的诊断信息采用对数化累积处理方法,并归一到同坐标下对比分析。结果表明,两类特征信息在故障诊断中表现高度相关。该研究为设备多信息融合故障诊断提供一条新的分析方法。Tribological system of gearbox was selected as the research object,and the analytic model of fault diagnosis correlation for tribological information and dynamic information of gears was set up through analyzing the similarities and differences between tribological information and dynamic information of gears.These two different dimensional diagnosis information employed the logarithmic and accumulative treatment were normalized to the same coordinates to analyze in the model.Result shows that it is the high correlation of these two kinds of characteristic information during the equipment fault diagnosis.This research provides a new analytical method for the equipment fault diagnosis of information fusion.
