PENGEMBANGAN DESAIN CIRCULAR DAN SQUARE CRASHBOX DENGAN PENAMBAHAN HONEYCOMB SEBAGAI FILLER PADA MODEL BEBAN FRONTAL DAN OBLIQUE

In the previous study, several researchers had developed circular and square crash box designs to enhance energy absorption. this honeycomb filled is investigated by varying cell dimension. Honeycomb selected due lightweight high strength weight ratio. The modelling was carried out using finite element method with a frontal oblique load model. dimensions vary five models, which are 0%, 25%, 50%, 75% 100%. This ratio compares size of pitch inner diameter box. thickness 40 mm 2 mm, respectively. single wall double 0,5 1 model used an impactor mass 600 kg speed 15 m/s. For model, angle for 300. absorption, deformation pattern efficiency collision force (CFE) were observed, based on results computer simulations. show that 25% (S25) has highest both loading. Otherwise, circle (C25) CFE value loading, S50 reaction-displacement curve, quite stable. S25 diamond mode folds. shows higher number fold than other models. Whereas, generates greater folding cells.
