Abstract(in English) | 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 is a structural optimization method that achieves the desired objective function by controlling the arrangement of materials, including voids, within the design area. 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 aim to make the uniform output surface vibration of the ultrasonic bonding tool using the level-set type topology optimization using domain remeshing. |
