摘　　要：油液光谱分析是综合传动装置磨损状态监测的重要手段,基于油液分析样本数据量有限和样本值变化具有随机性的特点,选择灰色GM模型进行磨损量预测。根据油液分析数据变化规律,介绍综合传动装置灰色建模的具体步骤和方法,提出当磨损速率偏高时基于灰色建模进行加密取样时刻预报的方法。实验证明,基于灰色建模的加密取样时刻预报方法,能够及时扑捉综合传动装置异常磨损故障征兆,避免重大故障发生。The state of power-shift steering transmission can be studied conveniently and timely by using spectral analysis of oil.The limitation and randomicity of sample data is the reason why grey modeling can be used to predicate the wear of power-shift steering transmission.The grey modeling method was proposed based on change rule of oil analysis data,and the method of predicting the sampling time was put forward when wear rate of power-shift steering transmission was too high.The experimental results show that the prediction method of sampling time based on grey modeling can help to diagnosis wear fault of power-shift steering transmission.
