摘　　要：外圆柱功率超声珩磨是一种精密、有效的外圆柱加工技术,对外圆柱功率超声珩磨磨削力的研究是深入研究其材料去除机理的关键。在对外圆柱功率超声珩磨切削机理及运动学分析的基础上,通过假设油石磨粒分布及切刃高度符合正态分布,推导出了油石条上总的动态有效磨粒数,在此基础上建立了外圆柱功率超声珩磨单颗磨粒的磨削力模型,最后对不同参数下磨削力的影响趋势进行了定性分析,为进一步研究外圆柱功率超声珩磨技术提供了理论基础。The outer cylinder power ultrasonic processing technology, the research of the outer to the depth study of its mechanism of material honing is a sophisticated and effective outer cylindrical cylinder power ultrasonic honing grinding force is the key removal. Through the derivation of Whetstone strips total number of dynamic effective abrasive by assuming that the Whetstone abrasive distribution and the height of the cutting edge is fitting the normal distribution, the outer cylinder power ultrasonic honing single ab- rasive grinding force model is established on the basis of the cutting mechanism and kinematic analysis of outer cylinder power ultrasonic honing. The impact trend of the grinding force is qualitatively analyzed in the different parameters, which provide theoretical foundation to the further study of the outer cylinder power ultrasonic honing technology.
