深滚压是一种广泛应用的机械表面和亚表面处理方法。它通常在传统加工后使用，以改善粗糙度、增加表面硬度并产生压缩残余应力。对表面形貌的主要影响参数是所施加的深滚压力、球直径和进给量。一般来说，低进给量、较大的球直径和较高的压力会产生均匀的表面光洁度。然而，精确预测粗糙度是不可能的。因此，本研究的目的是找到一种普遍适用的方法来预测各种钢和铝材料的深轧后表面粗糙度。结果表明，可以通过解析模型高精度地预测表面形貌。
Deep rolling is a widely applied mechanical surface and subsurface treatment method. It is typically used after conventional machining to improve the roughness, increase the surface hardness and to induce compressive residual stresses. The main influence parameters on the surface topography are the applied deep rolling pressure, the ball diameter and the feed. In general, low feeds, larger ball diameters and higher pressures result in an even surface finish. However, an exact prediction of the roughness is not possible. Therefore, it is the aim of the presented research to find a generally applicable method for surface roughness prediction after deep rolling for a variety of steel and aluminum materials. It is shown that the surface topography can be predicted by an analytical model with high accuracy.
