利用齿轮机构运行时的振动和噪声信号,对齿轮的磨损程度进行模式识别,齿轮磨损依程度轻重分为三类。采用二级两类线性判决结构,比三类一级判别方法的判别效果好。 The use of gear mechanism vibration and noise signals during operation, the gear wear pattern recognition, gear wear according to the degree of severity is divided into three categories. Using two levels of two linear decision structure, discrimination than the three levels of a discriminant effect is good.
