초음파 용접용 실린더 혼의 설계 = Design of Cylinder Horn for Ultrasonic Welding

다국어 초록 (Multilingual Abstract)

The cylinder horn is designed to increase uniformity of the displacement on the output face through simulation and experiments for the simple cylinder, spool and step horns. The modal analysis is conducted numerically to calculate the vibration mode and stress distribution of the cylinder horn, and the design of experiment (DOE) technique is employed to determine the optimum configuration of the spool horn. Displacement of the cylinder horn was measured using the Laser Doppler Vibrometer (LDV), and experimental results show good agreements with the predicted results. It appears that uniformity higher than 95% can be achieved with the spool horn when the proper dimension of the groove is used.
