| 中文摘要: |
| 为了研究7075航空铝合金在超声椭圆振动切削（Ultrasonic Elliptical Vibration Cutting, UEVC）下切削速度、背吃刀量、振幅和频率对切削力和切削温度的影响。课题组运用ABAQUS有限元软件建立了仿真模型，对比分析了不同切削方式对航空铝合金力学性能的影响。仿真结果表明：在UEVC过程中，随着切削速度和切深的增加，切削力逐渐增加，切削温度逐渐升高；随着X方向的振幅和振动频率的增加，切削力和切削温度逐渐降低；背吃刀量对切削力的影响最为明显。与常规切削（Conventional Cutting, CC）相比，UEVC能够明显降低切削力和切削温度，是一种改善航空铝合金切削性能的有效加工方式。 |

| In order to study the influence of cutting speed, cutting depth, amplitude and frequency of 7075 aviation aluminum alloy under UEVC (Ultrasonic Elliptical Vibration Cutting) on cutting force and cutting temperature, a simulation model was established by Abaqus finite element software, and the influence of different cutting methods on the mechanical properties of aviation aluminum alloy was compared and analyzed. The results show that in the UEVC process, with the increase of cutting speed and cutting depth, the cutting force and the cutting temperature increase gradually; with the increase of amplitude and vibration frequency in X direction, the cutting force and cutting temperature decrease gradually; the cutting depth has the most obvious effect on cutting force. Compared with CC (Conventional Cutting), UEVC can significantly reduce the cutting force and cutting temperature, which is an effective machining method to improve the cutting performance of aviation aluminum alloy. |
