Article Preview

Abstract:

Based on the theory of acoustic propagation, the realization mechanism of longitudinal-torsional vibration (LTV) by converter of cylinder with multiple diagonal slits (MDS) under single excitation was studied. The influences of composite stepped horns structural parameters on resonant frequency were studied by numerical analysis method, and the horn (resonant frequency about 20kHz) with LTV was designed. The results show that LTV could be realized under single excitation of longitudinal vibration when resonant frequency is 20498Hz, and the amplitude varied periodically. The results can be applied in the design of acoustic system in ultrasonic machining with LTV.
