摘要

传统的超声波焊接采用线性振动,但采用椭圆轨迹焊接可提高焊接强度。因此,我们开发了一种使用单个纵向振动传感器产生椭圆轨迹的振动源。虽然以前已经报道过椭圆轨迹的振动源,但它们都是采用等效传输线方法设计的。本文采用有限元方法对椭圆振动源进行了设计,制作了一个振动源并对其特性进行了测量。使纵向振动和扭转振动的共振频率更接近,可以在单一频率下获得椭圆轨迹的振动。

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.
