摘要：设计一套外圆超声珩磨装置，借助ANSYS软件对该装置的变幅杆和珩磨头进行整体动力学分析。在相同加工参数下分别采用传统的普通外圆珩磨和附加超声的外圆珩磨对SUS304不锈钢外圆柱表面进行加工试验。在试验中采用单因素变量法，分别改变工件回转速度与珩磨深度，对比外圆超声珩磨与普通外圆珩磨的加工效果，研究影响工件表面质量的主要因素。试验结果表明：珩磨深度、工件回转速度是影响表面粗糙度的主要因素，与普通外圆珩磨相比，附加超声的外圆珩磨表面粗糙度降低约10%。

Abstract:A set of outer cylindrical ultrasonic honing device is designed，then the dynamic analysis of the horn and honing head body is carried out by means of ANSYS software. Under the control of the same processing parameters，the outer cylinder surface of SUS304 stainless steel is tested by traditional conventional cylindrical honing and ultrasonic outer cylindrical honing.In the experiment，the single factor variable method is used by changing the workpiece rotation speed and honing depth respectively.By comparing with the effects of ultrasonic outer cylindrical honing and conventional cylindrical honing，the principal factors affecting the surface quality of the workpiece are studied.The results show that the honing depth and the workpiece rotation speed are the main factors influencing the roughness of the workpiece，the surface roughness in the test of ultrasonic outer honing is lower than that of the conventional outer honing test about 10%.
