Key Factors Affecting the Amplitude of a Composite Ultrasonic Wiredrawing Vibration System

Abstract

This paper studied the key factors affecting the amplitude of a composite ultrasonic wiredrawing vibration system, for designing a powerful ultrasonic vibration system. The finite element analysis (FEA) was performed. The results showed that the variable cross-section shapes of horns and the angles between the connection of both ends of the cross-section and the center line had great effects on the amplitude of an ultrasonic vibration system. In order to valid the theoretical result, the experiments were carried out on a composite ultrasonic vibration system. The experimental result demonstrated that the conical variable cross-section rods used in an ultrasonic vibration system produced large amplitude.

A new piezoelectric ceramic longitudinal–torsional composite ultrasonic vibrator for wire drawing

“…As for ultrasonic wire drawing, longitudinal vibration and radial vibration have been mainly adapted to study the advantageous impacts [1,2]. However, few researches with respect to the effects of longitudinal-torsional (L&T) composite vibration on wire drawing can be found.…”
