本文描述了一种高精度滚动导轨支承的直线传动系统中干扰力的表征方法。干扰力分为摩擦力和其他干扰力。提出了分析全局位置效应、微观位置效应和转台速度效应的实验表征方法。对由直线电机和滚动导轨组成的定位系统进行了停-停-走和反向运动的特性实验和分析。首先，全局扰动力依赖于全局位置，并对粘滑摩擦分量进行了表征。其次，在微观区域将粘着摩擦力与粘着摩擦力和滑动摩擦力分离。第三，分析了速度的影响。最后，用修正的单刚毛模型描述了微观区的摩擦特性，模拟了所测得的干扰力。
This paper describes a characterization method of disturbance force in a linear drive system supported by high-precision rolling guideways. Disturbance force is divided into the friction component and other disturbance force. Experimental characterization method to analyze effect of global position, effect of micro-position and effect of table velocity is suggested. With stop-dwell-go and reversal motions, characterization experiment and analysis are conducted on a positioning system consists of a linear motor and rolling guideways. Firstly, global disturbance force depends on global position and stick and slip friction components are characterized. Secondly, stick friction force is separated from stick and slip friction force in the micro-region. Thirdly, influence of the velocity is analyzed. Finally, a modified single bristle model, which describes friction characteristics in the micro-regime, is shown to simulate the measured disturbance force.
