摘　　要：胶辊的摩擦特性直接影响打印机的分纸效果,文中在橡胶的粘弹性标准线性固体模型理论上,建立了胶辊与纸张间的滚动摩擦接触模型,推导出胶辊的接触应力分布函数与滚动摩擦系数表达式。matlab数值分析及实验结果表明:胶辊的滚动摩擦接触应力成不对称分布;压力和转速对胶辊的滚动接触区宽度、宽度比与摩擦系数有影响。The effect of paper feeding in printer is influenced directly by the friction characteristics of rubber roller. Based on the viscoelastic theory with standard linear solid model of rubber, the frictional contact model between rubber roller and paper is established. The distribution function of contact stress and the equation of rolling friction coefficient is also obtained. The result of numerical analysis and experiment with Matlab indicates that the distribution of contact stress is asymmetric, and both the rotational speed and stress influence the contact width, the width ratio and the friction coefficient.
