摘　　要：平台珩磨是目前被广泛应用的一种发动机缸孔精加工工艺,珩磨后缸孔的表面粗糙度直接影响缸孔的摩擦磨损性能。针对某型发动机缸孔的平台珩磨工艺,采用正交试验的方法研究平台珩磨转速、粗珩进给率、精珩时间对缸孔表面粗糙度的Abbott参数(波峰平均高度Rpk、波谷平均深度Rvk)和加工效率的影响规律。研究结果表明:珩磨转速对Rpk、Rvk的影响最大,其次为精珩时间,粗珩进给率对其影响很小;而通过提高粗珩进给率,能够在不显著改变缸孔表面粗糙度的条件下,大幅度提升平台珩磨加工效率。Plateau honing is a widely used method for the finishing of engine cylinder bores. Plateau honing forms the surface topography of cylinder bore which has a direct effect on the engine friction and wear performance. The influence of plateau honing process parameters （honing rotation speed, rough honing expansion speed, finish honing duration） on cylinder bore surface roughness parameters （peak roughness Rpk, valley roughness Rvk） and plateau honing efficiency is studied by means of orthogonal experiments. The result shows that honing rotation speed is the most principal influence factor on Rpk and Rvk; finish honing duration is the second most principal factor, and rough honing expansion speed does not have major influence on Rpk and Rvk. Plateau honing efficiency could be improved by increasing rough honing expansion speed without significantly changing the surface roughness of cylinder bores.
