摘要
Abstract It has been reported that ultrasonic welding using planar vibrations results in higher weld strength and less damage to the work pieces compared with ultrasonic welding using linear vibrations. However, torsional vibration transducers are small and expensive, thus reducing flexibility in the use of the vibration source. Therefore, in this study, we developed an ultrasonic longitudinal-torsional vibration source using longitudinal vibration transducers and a uniform rod with diagonal slits. The proposed vibration source generates torsional vibration by using a uniform rod with diagonal slits instead of a conventional torsional vibration transducer. As a result, it is found that a planar vibration locus is obtained by inputting two resonance frequencies simultaneously.
