Crash boxes is important equipment in supporting transport safety. This study aims to investigate the performance of a circular tube. The investigation is carried out using a finite element-based software simulation. The tube is 300 mm long with 1.5 and 3 mm thick variations and 120 mm diameter. The crash box simulation will be conducted using a quasi-static test model with a 200 kg impactor and 10 m/s velocity. The crash box simulation is observed based on SEA (Specific Energy Absorption), MF (Mean Force), IPFC (Initial Peak Force), CFE (Crush Force Efficiency), and EA (Energy absorption). The simulation results show that the 3.0 mm thick crash box tube can produce an energy absorption value of 790000 Joules. The tube tends to form concertina deformation. Tubes with a thickness of 1.5 mm tend to experience buckling, so they have lower energy absorption. The selection of tube thickness is worth considering when designing an efficient crash box in the future. © 2025 Author(s).
