    Abstract: A method and apparatus for determining the resonance frequency for a vibration welder (12) are described. The vibration frequencies at a predetermined vibration level and on both sides of the resonance frequency are derived and are then used to determine and operate the vibration welder (12) at the resonance frequency. In one embodiment the vibration frequency of the vibration welder (12) is swept up from one side of the resonance point and the vibration amplitude is monitored and a first frequency at a particular vibration amplitude is determined. The same sweeping is done from the other side of the resonance point and a first frequency at a particular vibration amplitude is determined. The same sweeping is done from the other side of the resonance point and a second frequency determined for the same vibration amplitude reference level but on the other side of the resonance frequency. The two measured frequencies are then combined to yield the resonance frequency which can then be used to operate the vibration welder (12).

    Abstract: Methods of mitigating current overload of an ultrasonic system having an ultrasonic stack under load at startup are provided. The methods include beginning an ultrasonic cycle in the ultrasonic system having the ultrasonic stack that runs a closed loop phase control through the weld cycle by ramping up the power of the ultrasonic stack under load. During ramping up of the power of the ultrasonic stack under load, a controller lowers the phase to a negative phase. After ramping up the power of the ultrasonic stack under load is complete, the controller raises the phase to 0 degrees and the ultrasonic stack is operating at steady state and with the phase at 0 degrees.

    Abstract: A method for controlling, in particular damping, a mechanical oscillation of a system, in particular for vibration welding, wherein in a first time period the system is excited with an exciting signal which has a first frequency value f1, with the result that a first time profile p(t) of the phase of the exciting signal is present, in a second time period the system is excited with a frequency value profile f(t), which varies over time and is selected in such a way that, at the end of the second time period, the time profile of the phase of the exciting signal as a non-diminishing phase difference Delta_p at the first time profile p(t) of the phase, wherein the frequency value profile f(t) starts at the beginning of the second time period with the first frequency value f1, and at the end of the second time period it ends with the first frequency value f1, in particular wherein the frequency value profile f(t) is continuous, in particular is continuous and can be differentiated continuously.
