摘要
将纵-扭复合超声振动引入到传统深滚加工中,创建纵-扭复合振动超声深滚加工工艺,阐述其加工原理;分析其滚压过程;建立其表面形成模型并理论分析表面形貌形成机理;试验对比研究两种滚压方式下工件表面的微观形貌。试验结果表明:在相同的工艺参数下,辅助纵-扭复合振动后,工件的表面微观形貌优于传统深滚加工所获得,试验结果与理论分析结果相吻合。
Ultrasonic deep rolling with longitudinal -torsional vibration （UDR -LTV）is created by introduction of ultrasonic machining with longitudinal -torsional vibration between conventional deep rolling. The principle of UDR - LTV and the rolling process are elaborated. The surface model is established and the formation mechanism of surface topography is analyzed theoretically. The surface microscopic morphology is researched by experimental comparison under the two types of rolling method. The results indicate that： with the same processing parameters, the surface microscopic morphology obtained by UDR - LTV is better than that of CDR. The experiment results with the theoretical analysis results are identical with each other.
