摘要:
针对目前纵扭共振超声加工系统中存在的振动方向单一、加工难度大等问题,该文设计一种新型螺旋槽式纵扭超声加工系统,通过数值计算法对纵扭超声加工刀柄进行了结构设计,运用有限元软件Workbench分析结构参数对超声振动系统谐振频率的影响规律,并在此基础上对纵扭超声加工系统进行瞬态分析。仿真结果表明,该旋转超声加工系统能够实现纵扭超声振动,且谐振频率与设计值误差为 1.675%,振幅可达到预期要求。最后对该纵扭超声系统进行振幅测试,实验结果表明,纵振振幅为9.3 μm,扭振振幅为4.5 μm,验证了该文设计方法的合理性和正确性。
Abstract:
Aiming at the problems of single vibration and processing difficulty in the current longitudinal-torsional ultrasonic machining system,a new longitudinal-torsional ultrasonic machining system with helical grooves is designed in this paper. The structural design of the longitudinal-torsional ultrasonic machining tool holder is theoretically calculated. The Workbench is used to analyze the influence of various structural parameters on the resonant frequency of the ultrasonic vibration system,and the ultrasonic processing system is analyzed transiently. The results show that the transducer can achieve longitudinal-torsional ultrasonic vibration,and the error between the resonant frequency and the design value is 1.675%. The amplitude can meet the expected requirement. Finally,the amplitude test of the longitudinal-torsional ultrasonic tool holder shows that the longitudinal vibration amplitude is 9.3 μm and the torsional vibration amplitude is 4.5 μm. The correctness of the design method is also verified.
