Uniform vibration of ultrasonic bonding tools is important for industrial applications, but its design requires a great deal of expertise due to wave effects. Topology optimization using level-set functions progresses with a clear interface rather than grayscale density, so that when the optimization results are actually fabricated, there is little error in terms of resonance frequency and other optimization performance. In this study, we perform an optimization to obtain an uniform vibration distribution by using a commercial finite element software to create a three-dimensional model by extruding a shape obtained from a level-set function in two-dimensional space. The tool obtained from the optimization is actually fabricated and the transducer performance and vibration distribution are measured. |
