摘　　要：基于压电陶瓷的逆压电效应,设计了一种超声振动辅助粉末去除装置,用于去除挂钩表面粘附的粉末。使用有限元分析软件ANSYS对超声振动系统中的振子进行了结构动力学模态分析、谐响应分析和瞬态分析,得出了振子的振动模态、谐振频率、幅频曲线、导纳曲线、导纳圆和瞬态振动曲线及相关数据,对后期该振子的制作以及超声振动辅助粉末去除装置的实现起到了重要的理论指导作用。Based on the reverse piezoelectric effect of piezoelectric ceramics,a kind of powder removal device which is assisted by ultrasonic vibration is designed to remove the powder attached to the hook surface.The dynamic modal analysis,harmonic response analysis,and transient analysis of the vibrator in the ultrasonic vibration system are carried out by use of ANSYS,and the vibration mode,resonance frequency,amplitude frequency curve,admittance curve,admittance and transient vibration curve are obtained.It may play an important theoretical guiding role in the production of the oscillator and the realization of the ultrasonic vibration auxiliary powder removal device.
