摘要

研究了100 kHz复杂振动超声搭接点焊系统。复杂振动焊头在椭圆轨迹上振动。采用铝板试件，比较了100 kHz、60 kHz、40 kHz和27 kHz纵扭变换器复合振动系统的焊接特性。铝板的焊接与焊尖振动方向和试样方向无关。当振动频率变高时，获得足够焊接强度所需的焊接系统的振动幅值变小。其中，100 kHz系统下铝板试件所需振动幅值最小。

Ultrasonic complex vibration welding system using 100 kHz one-dimensional longitudinal-torsional vibration converter

Complex vibration ultrasonic lap spot welding systems of 100 kHz are studied. The complex vibration welding tip vibrates in elliptical locus. Welding characteristics of 100 kHz, 60 kHz, 40 kHz and 27 kHz complex vibration systems with a longitudinal-torsional vibration converter were compared using aluminum plate specimens. Aluminum plates were welded independent to the directions between welding tip vibration direction and specimens. The vibration amplitudes of the welding systems required for obtaining sufficient weld strength become smaller, as the vibration frequencies become higher. The required vibration amplitude of aluminum plate specimens the 100 kHz system was smallest among them.
