| contents | In this research, multi-physics topology optimization is employed to achieve the detailed design of a lightweight porous linear actuation mechanism that harnesses energy through laser activation. A multiscale topology optimization methodology is introduced for micro- and macroscale design, considering energy dissipation via heat convection and radiation. This investigation meticulously considers the impact of heat dissipation mechanisms, including thermal conduction, convection, and radiation. Through various numerical cases, we systematically explore the influence of micro-scale considerations on porous design and understand the effects on the topology optimization process by incorporating various microstructural systems. The results demonstrate that porous actuator designs exhibit superior performance compared to solid actuator designs. This study contributes to advancing the understanding of multiscale effects in topology optimization, paving the way for more efficient and lightweight designs in the field of laser-activated porous actuators. |
