摘　　要：预滑动摩擦是机械系统中具有相对运动的接触面发生粘着时的一个重要摩擦现象,其建模的恰当与否直接关系到系统的定位精度、动力学特性以及控制补偿。针对预滑动摩擦的建模,重点介绍了几种描述预滑动摩擦的数学模型,并对各种模型的特点分别加以讨论。同时针对模型参数辨识和应用方面作以简要论述,为以后预滑动摩擦的建模以及应用提供了参考。Pre-sliding friction is an important phenomenon in mechanical systems when the contact surfaces with relative movement are sticking. The accuracy of the friction model directly affects the position precision, dynamic characteristics and friction compensation of mechanical systems. A few of mathematical models describing pre-sliding friction were introduced mainly, and the characteristics were discussed individually. Furthermore, the parameter identification and the application of the friction models were discussed briefly. All of these have provided references for modeling and application of pre-sliding friction in the future. At last, some advice has been proposed.
