This study aimed to design and verify ultrasonic knife modules, which have experienced a recent surge in demand. To this end, ultrasonic transducers and horns with longitudinal vibration characteristics of 40 kHz grounded in theoretical equations were designed. Subsequently, tensile experiments on materials were conducted and applied for precise wavelength analysis. Modal and harmonic response analysis using CAE was performed to predict vibration characteristics and natural frequencies for the designed ultrasonic knife. As a result of the analysis, the study revealed that the knife had an intrinsic frequency characteristic of about 38.1 kHz and vibrated in the axial direction. An ultrasonic knife, stemming from these findings, was manufactured and confirmed to achieve equivalent performance to the design, through resonance frequency analysis and vibration mode analysis.
