摘要：A method of minimizing mechanical resonance in an assembly during formationof a vibration-welded joint therein includes positioning work pieces such that they aredirectly adjacent to each other, and generating a set of control signals that cause one ormore sonotrode weld heads to vibrate. A waveform characteristic of a mechanicaloscillation of the sonotrode(s) and weld head(s) is varied to minimize the mechanicalresonance occurring in the assembly, such as a multi-cell battery for a vehicle. Anapparatus for forming the welded joint includes at least one sonotrode having a weldhead or heads formed integrally therewith, and a weld controller. The controller isconnected to a converter, sonotrode(s), and weld head(s), with the mechanical oscillation

occurring in the sonotrode(s) and weld head(s). Variation of the control signals duringformation of the welded joint varies a waveform characteristic of the mechanicaloscillation, thus minimizing the mechanical resonance.
