First, the key components of such a system, such as an ultrasonic stack (con- sisting of a high power ultrasonic transducer and a sonotrode) and a digitally controlled ultrasonic power supply with precise control of the output power, have been considered. Next, a concept of measurement system for verification and validation of mathematical models of ultrasonic stacks and its components has been presented. Finally, a method of ultrasonic stack e-diagnosis based on ultrasonic transducer electrical impedance measurement during welding and cutting process has been described}, type={Artykuły / Articles}, title={Modelling and Designing of Ultrasonic Welding Systems}, URL={http://ochroma.man.poznan.pl/Content/101371/PDF/11_paper.pdf}, doi={10.1515/aoa-2015-0011}, keywords={ultrasonic welding and cutting system, ultrasonic stack modelling and designing, digitally controlled ultrasonic power supply, ultrasonic stack e-diagnosis}, }
