Sun: Numerical analysis of anvil vibrations during Ultrasonic Metal Welding
2023-05-26 @ 11:00 - 12:00
Ultrasonic Metal Welding (USMW) is a widely used manufacturing technology for joining metal components in modern industry. The metal sheets which are placed above the anvil need to be bonded. The sonotrode, which is also called the horn, vibrates at high frequency and on the top of the metal sheets. The constant clamp force applied on the metal sheets from the horn produces friction force between two metal sheets and makes them join together. The joining strength is the most important aspect of the welding process. However, it is impossible to directly measure the joining strength in reality. One way to estimate the joining strength is by measuring the vibrations of the horn and the anvil and using these measurement data to compute the vibrations of the welding area which can represent the joining strength during the welding process. Therefore, the goal of this thesis is to use the simulations with COMSOL and measurements by Laser Doppler Vibrometer (LDV) to help us learn more about the physical behavior of the anvil during the welding process.
