This article presents the experimental and simulation analysis of the energy absorption capacity of a 3D printed structure design. The study focuses on investigating the influence of the honeycomb structure with various orientations on its energy absorption capacity under various loading conditions. Finite element analysis (FEA) simulations are used to predict the energy absorption capacity of different honeycomb structures under compression and impact loading conditions. ANSYS software is utilized for explicit dynamics simulation, which is effective for situations involving large deformation and contact-dominated behavior. Meshing is a critical step in the simulation process as it directly affected the accuracy and efficiency of the results. The experimental analysis is carried out by subjecting the 3D printed honeycomb structure to compression and impact tests, and the results are compared with the simulation data. The study found that the geometrical design optimization of the honeycomb structure can significantly improve its energy absorption capacity. The article contributes valuable insights for the design and optimization of 3D printed honeycomb sandwich structures for energy absorption applications.
