基于激光粉末床熔融成形的Gyroid结构参数化调整对其压缩力学行为的影响
Effects of Parametric Modification of Gyroid Structures Fabricated via Laser Powder Bed Fusion on their Compressive Mechanical Behavior
摘要
Abstract
Based on the laser powder bed fusion(LPBF)technique,the effects of parametric tuning on the compressive mechanical behavior of Gyroid triple-periodic minimal surface(TPMS)structures has been systematically investigated,and the correlation laws between the structural parameters and the mechanical properties are revealed through tuning the key parameters such as structure cell size,wall thickness and neutral plane offset,and combining experimental and numerical analyses.The results show that each 0.1 mm increase in wall thickness can increase the yield strength by 25%-50%,and the compressive strength increases significantly;decreasing the cell size can significantly increase the compressive strength(145-600 MPa)and yield strength(80-240 MPa);and the peak densification value of the neutral plane offset value of C=±0.3 reaches 40.1%,which is optimal for the mechanical properties.It is found that the synergistic regulation of wall thickness and neutral plane offset can balance the lightweight and load-carrying requirements,providing theoretical basis and experimental support for the parametric optimization of TPMS structures in aerospace and automotive lightweight design.关键词
