Effect of non-linear finite element analysis for honeycomb filler structure.
Crashworthiness is the most important part in designing a safety vehicle. Therefore, the types of collisions, crashworthiness parameter and the modes of collapse of structural components are important indicators of design. Energy absorbing device is an important part during design. An effective energy absorbing device capable dissipates kinetic energy during collision is desired. Honeycomb filler is known as good filler for the energy absorbing device. Meanwhile, in real situation during accident, the collision is not only from the frontal impact (axial loading), it also may from different angle (oblique loading). Different angle of impact loading may affect the performance of the energy absorbing device. In this study, the investigation is carry out by Finite Element (FE) simulation with using ABAQUS software. The investigations of all FE model are carried out by dynamic impact test. Three types of honeycomb filler geometric designs which are circular honeycomb filler, hexagon honeycomb filler and multi-cell. The dimensions of honeycomb filler with two different thicknesses are investigated. From the result, by increased thickness from t = 0.06mm to 0.12mm, the energy absorption (EA) and specific energy absorption (SEA) increased 290% and 140% respectively. In conclusion, the result showed that hexagon honeycomb filler is the best model among the honeycomb filler.
