Abstract:
A honeycomb column thin-walled structure (HCTS) was designed and the relative density was calculated for numerical simulation. The HCTS samples were fabricated via selective laser melting (SLM). The numerical simulation and a three-point bending test were conducted to evaluate the mechanical properties of the HCTS made of Ti6Al4V. The findings of the numerical simulation demonstrated that the HCTS had a stronger resistance to deformation and a maximum loading force 30% higher than the equivalent solid thin-walled structure (ESTS). The mechanical performance of the HCTS as determined by the three-point bending test was mostly comparable with the numerical simulation. The maximum loading force of the experimental HCTS050-E thin-walled structure was 1200 N higher than that of HCTS050-S. The numerical simulation can provide theoretical guidance for the SLM processing of HCTSs.
