Laser-Activated Lightweight Porous Linear Actuation Micro Mechanisms through Multiscale Topology Optimization with Considering Radiation

Musaddiq Al Ali,
Masatoshi Shimoda

Abstract: This study applies multi-physics concurrent multiscale topology optimization to develop a lightweight porous linear actuation mechanism activated by laser energy. It meticulously explores thermal dissipation mechanisms, incorporating conduction, convection, and radiation dynamics. By examining various numerical cases, the study reveals a substantial 45% performance improvement in porous designs compared to solid actuators. The investigation extends to simultaneous optimization of multiscale porous displacement… Show more
