Development of an ultrasonic complex vibration source that produces an elliptical vibration locus
: Conventional ultrasonic welding uses linear vibrations, but welding using an elliptical locus improves welding strength. Therefore, we developed a vibration source that generates an elliptical locus using a single longitudinal vibration transducer. Although vibration sources with an elliptical locus have been reported previously, they were designed using the equivalent transmission line method. In this paper, we used the finite element method to elliptical vibration source design, and we fabricated a vibration source and measured its characteristics. Bringing the resonance frequencies of the longitudinal and torsional vibration closer together allowed vibration with an elliptical locus to be obtained at a single frequency.
期刊介绍:
Acoustical Science and Technology(AST) is a bimonthly open-access journal edited by the Acoustical Society of Japan and was established in 1980 as the Journal of Acoustical Society of Japan (E). The title of the journal was changed to the current title in 2001. AST publishes about 100 high-quality articles (including papers, technical reports, and acoustical letters) each year. The scope of the journal covers all fields of acoustics, both scientific and technological, including (but not limited to) the following research areas. Psychological and Physiological Acoustics Speech Ultrasonics Underwater Acoustics Noise and Vibration Electroacoustics Musical Acoustics Architectural Acoustics Sonochemistry Acoustic Imaging.
