Configurations of Large Capacity Ultrasonic Complex Vibration Sources with Complex Transverse Vibration Rods and a Disk with Multiple Transducers

Abstract

The ultrasonic complex vibration systems with elliptical to circular locus are effective and essential for new high power applications in various industries. Configuration of a 27kHz and a 40kHz complex vibration source with a complex transverse vibration rod with a welding tip part and a longitudinal and transverse vibration disk with six and four bolt-clamped Langevin type PZT longitudinal transducers and welding characteristics of aluminum and aluminum alloy plates using complex vibration systems were studied. Outer diameters of the 40kHz complex vibration sources are 191 to 195mm which are about half of the diameter 395mm of the 27kHz vibration source. Stepped complex transverse-vibration rods with a welding tip is installed in the center of the disk and is driven in circular vibration locus at the free edge of the rod (welding tip) using three and two 500W power amplifier systems.
