DESIGN AND ANALYSIS OF A LOW FRICTION TANTALUM POWDER FORMING MOULD UTILIZING MULTI-WAVELENGTH EXCITING MODE
Tantalum capacitor has been widely used in many fields of electrical,communications,automotive,military,aerospace,etc.This paper proposes a low frictional mould of tantalum capacitor,and the ultrasonic friction reduction is realized by an ultrasonic transducer driven by twelve rectangular piezoelectric plates.The forming pressing mould mainly contains top convex mould,top adjusting shim,ultrasonic transducer,bottom convex mould,and bottom adjusting shim.The rectangular piezoelectric plates are bonded to the opposite outside surfaces of ultrasonic transducer and the d31 working mode is adopted.The composite exciting method of the forming pressing mould is clarified in detail.The modal shape of the ultrasonic transducer is analyzed using Finite Element Method(FEM).The prototype is fabricated and tested.The testing results indicate that the vibration performance of the motor is in good agreement with the simulation results.
