TPMS MICROSTRUCTURAL MATERIAL WITH HOLES AND OPTIMIZATION DESIGN METHOD THEREFOR

摘要

A TPMS microstructural material with holes and an optimization design method therefor are related to the technical fields of topology optimization, microstructural materials and 3D printing. TPMS is smooth, has a large specific surface area and good mechanical properties, and has a good application prospect in the field of microstructural material design. According to the optimization design method, an advanced design method, i.e., topology optimization, is applied to the microstructural material design based on TPMS. The method is to conduct topology optimization on a TPMS model, and then design the number, layout and shape of holes in a complete TPMS according to the results of topology optimization so as to obtain the microstructural material with different configurations. The material obtained has a higher utilization rate and a better lightweight property.
