摘要：

为获得超声滚挤压强化7050铝合金过程中加工参数对表面粗糙度的敏感程度，开展超声滚挤压强化7050铝合金表面粗糙度正交试验，基于表面粗糙度试验结果，运用极差分析法、指数函数预测模型法、灰色关联分析法等确定加工参数对表面粗糙度的影响程度。研究结果表明：超声滚挤压强化7050铝合金过程中加工参数对表面粗糙度的影响程度依次为工件转速、静压力和进给速度；表面粗糙度的最优加工参数水平为：n为350 r·min-1、F为400 N、f为10 mm·min-1；3种不同方法相互检验，确定出的加工参数对表面粗糙度的灵敏程度一致。超声滚挤压强化过程中，合理控制对表面粗糙度影响显著的加工参数，能够实现工件表面质量达到最佳。

In order to obtain the sensitivity of the processing parameters on surface roughness in the process of ultrasonic rolling extrusion strengthening for 7075 alumiunm alloy, the orthogonal test on surface roughness of 7050 aluminum alloy strengthened by ultrasonic rolling extrusion was carried out, and based on surface roughness test results, the influence degree of processing parameters on surface roughness were determined by range analysis method, exponential function prediction model method and grey correlation analysis method. The results show that in the process of ultrasonic rolling extrusion strengthening for 7050 aluminum alloy, the order of influence degree of processing parameters on surface roughness is workpiece rotate speed, static pressure and feeding speed, and the optimal processing parameter level of surface roughness is n=350 r·min-1, F=400 N, f=10 mm·min-1. Furthermore, the three different methods are mutually tested, and the sensitivity of processing parameters on the surface roughness is consistent. Thus, in the process of ultrasonic rolling extrusion strengthening, the best surface quality of the workpiece can be achieved by reasonably controlling the processing parameters, which have significant influence on the surface roughness.
