摘要/Abstract

摘要： 为了实现基于磨削参数预测工件的摩擦性能，并减少测量真实表面形貌和开展摩擦磨损试验等环节，在考虑砂轮磨粒切削刃与工件运动干涉的条件下，结合单点金刚石修整和参数设定建立了磨削后的工件表面形貌模型，并利用混合润滑雷诺方程分析不同磨削形貌下的压力分布及摩擦系数.同时，以机床导轨磨削平面的润滑特性为例验证了所建模型的有效性.结果表明，当磨削表面上、下纹理方向夹角均为0° 时，摩擦副的摩擦系数最大.

Abstract: An approach for predicting the friction performance of workpieces with grinding parameters was proposed to reduce the costs of surface profile measurement and development of friction and wear experiments. Considering the movement interference between the cutting edge of the grinding wheel and the workpiece, a model of the workpiece surface topography with the given parameters was established by combining the single-point diamond dressing; then the pressure distribution and friction coefficient of the grinding morphology were obtained by combining with the Reynolds equation under mixing lubrication. Simultaneously, taking machine guideway as an example, the model established above was validated. The analysis shows that the maximum friction coefficient can be obtained when the angles of the upper and lower surface textures are all 0°.
