摘　　要：为了实现多边体的超精密加工,设计了多边体超声切边声学系统,利用解析法设计了变幅杆的结构尺寸及其性能参数,并采用ANSYS软件对变幅杆—工具系统进行了有限元仿真。利用HP4294A阻抗分析仪对超声切边声学系统进行了实验测试。实验结果表明测得的谐振频率符合设计要求,该声学系统可成功应用于实际生产。Aiming at realizing ultra-precision machining of multilateral body, the acoustic system of cutting multilateral body edge with ultrasonic was designed. Through the analytical method, the structure and the performance parameters of amplitude transformer were designed, and the amplitude transformer--tool system was simulated with the ANSYS. Finally the experiment of ultrasonic acoustic system was carried out by the HP4294A impedance analyzer. The results show that resonant frequency could comply with design requirements and prove that the acoustic system could apply to actual production successfully.
