摘　　要：基于有限元分析方法,对新型超声内圆磨削系统的振子、主轴部件等效模型进行整体特性分析研究,根据套筒长度、套筒壁厚对超声内圆磨削系统主轴振动模态的影响规律,提出了应用旋转式非接触电信号传输装置的新型超声振动内圆磨削系统的设计方法。使用激光多普勒测振仪对振子、主轴部件及超声内圆磨削系统样机进行了特性实验研究,验证了新型超声内圆磨削样机和理论设计方案的一致性。Based on the FEM, the properties of the overall vibrator and the overall shaft in new ultrasonic vibration internal grinding system were studied in this paper. The overall design method of new ultrasonic vibration internal grinding system by using rotary non-contact transmission device was proposed according to the influence of the sleeve length and thickness to ultrasonic vibration internal grinding system. Experi- ments about the vibrator, the shaft and the ultrasonic vibration internal grinding system were studied by using PSV-400 scanning vibrometer, and the consistency between the new ultrasonic vibration internal grinding prototype and theoretical design was confirmed.
