| 微细电火花技术凭借自身的特点和优势,在航空航天、医疗器械等领域发挥着重要的作用。超声振动辅助电火花加工在传统电火花加工中引入超声振动,加工精度和加工效率明显提高。作为核心部件,超声振动主轴的设计尤为重要。但传统设计过程,大大延长了研发周期和增加了成本，,因此,采用仿真方式进行研究具有重要的意义。本文对设计的微细电火花超声振动主轴的进行了仿真研究,通过ABAQUS进行了模态分析和谐响应分析,得到了超声振动主轴的谐振频率和输出振幅等参数。超声振动主轴的测试实验验证了仿真结果的正确性。 |

| With its own characteristics and advantages, micro EDM technology plays an important role in aerospace, medical devices and other fields. Ultrasonic vibration is introduced into traditional EDM, and the machining accuracy and efficiency are significantly improved. As the core component, the design of ultrasonic vibration spindle is particularly important. However, the traditional design process can greatly extend the R & D cycle and increase costs. Therefore, it is of great significance to study by simulation. In this paper, the simulation of micro EDM ultrasonic vibration spindle is studied. The modal analysis and harmonic response analysis are carried out by ABAQUS, and the resonant frequency and output amplitude of ultrasonic vibration spindle are obtained. The test results of ultrasonic vibration spindle verify the correctness of the simulation results. |
