SUMMARY:Uribe Corral: Vibroacoustic modelling of an ultrasonic metal welding process
DESCRIPTION:Ultrasonic Metal Welding (USMW) is solid-state bonding process where two metal pieces are joined by the application of ultrasonic vibrations. This thesis focuses on the study of the sonotrode during a free run to understand the airborne sound field generated during the welding process. \nSimulation data are generated using COMSOL Multiphysics to model the physics involved during USMW with different studies: solid mechanics time-dependent\, pressure acoustics transient and pressure acoustics\, boundary elements. Simulation results are presented using FEM and BEM methods\, with different 2D and 3D geometry models and including the effect of surface reflexions. \nFinally simulations and measurements are compared to find possible microphone positions for an acoustic monitoring method. \nMelden Sie sich hier an um die Einladung zu dem Vortrag per E-Mail zu erhalten.\nRegister here to receive the invitation to this talk via E-Mail. \nZoom-Meeting-ID: 934 4303 5464\nPasswort: 171751
