摘　　要：结合综合传动装置工作原理和液压润滑系统的结构特征,分析了油液分析状态监测与故障诊断的原理,介绍了综合传动装置油液分析数据预处理中补油修正方法和初始浓度转化方法。通过数学方法对采集油液浓度值进行修正,可排除补油造成的影响;对于起始浓度值不同、试验方法完全一样的油液分析数据,基于油液浓度值变化的规律,利用数学建模计算的方法,可将初始浓度转化为一致情况。According to the work principle and the structure characteristics of hydraulic lubrication system of the power- shift steering transmission, the principle of the condition monitoring and fault diagnosis in oil analysis was studied, and the fill oil modification method, the initial concentration transformation method were introduced. The effect of fill oil can be removed by using mathematic method to transform the initial concentration. If the experiment method is just the same, based on the change rule of oil concentration, the different initial concentration can be translated into the same by using modeling and calculation methods.
