摘　　要：针对在定纤感知器感知机制方面的学术争论问题,借用摩擦学理论,对感知器运动各个过程的摩擦性质进行定性归类。依据摩擦学对固体摩擦、边界摩擦、流体摩擦的定义,从建立的丝条与感知器接触的宏观模型、微观模型等方面进行分析,指出原有定纤感知理论模型存在的不足。利用摩擦学的简单黏着理论,重新建立丝条与感知器玻璃片接触的摩擦力公式。公式显示在正常感知情况下同时存在固体摩擦、边界摩擦、流体摩擦3种摩擦,当纤度直径小于感知器垫片厚度时,与原有定纤感知理论模型一致,认为新理论更适用于目前所用全部类型的自动缫丝机的管理。With a view to the academic debates about the mechanism of the glass denierer perception, the tribology theory was used and the friction nature of glass denierer in each movement processes was qualitative classified. By using the tribology to define the solid friction, the border friction, and the fluid friction and analyze the macro and micro model of the contact between the silk yarn and the glass denierer, the previous denierer theoretical model deficiencies were pointed out. The friction formula of the contact between the silk yarn and the glass denierer was re-established by using the simple adhesion theory which was from the tribology. The new friction formula of the contact between the silk yarn and the glass denierer shows that there are three frictions： the solid friction, the border friction, and the fluid friction in the normal perception circumstances. When the silk yarn size diameter is less than the thickness of sensor pad, the new friction formula of the contact between the silk yarn and the glass denierer is the same as the previous denierer theoretical model. Therefore, it can be said that the new theory is more applicable to all types of glass denierer now in use.
