“…This is different from previous research, if in previous research crash box was modeled as square, then in this research, the crash box was modelled as rectangle adjusted to real condition of MPV car, as seen in figure 3 and 4, with 2 mm thick crash box. The origami pattern crash box modeling was performed by taking optimum geometry data from previous research [11,12], which were number 3, 5 and 7 with segments of 6, 3 and 5 respectively. The result of crash box modelling design was seen in Figure 3 and 4, both of them had the same dimensions of length, width and height.…”

“…The next research is performed by Kusyairi, et al [11], they design the origami pattern crash box with the Taguchi method on high speed impact test, it is concluded that the origami pattern crash box is able to produce predictable collapse mode and the greatest absorption was geometry that has many and thick segments. Origami pattern crash box collision research on the direction of corner collision has also been performed by Bintarto et al [12] and Zhou et al [13], it is found that pre folded mode of origami pattern capable of producing predictable collapse mode. The development of origami pattern crash box on the addition of origami trapezoid geometry model is performed by Zhou et al [14] the development of origami pattern with reconfigurable polygonal cross-sections model is performed by Filipov et al [15] and the development of origami pattern on Axial crushing is performed by Song et al [16].…”

Crash box serves as a kinetic energy absorber during collision. It has a tube shape, which is located between bumper and chasis. The crash box design requires development in order to reduce buckling mode and obtain symmetry folding mechanism, so it will achieve greater energy absortion. The researchers find a method to reduce tension due to impact by providing dents in crash box geometry. This research observed origami pattern crash box design having dents functioned as pre-folded so that collapse mode can be predicted and stable. In this research, the crash box was modeled according to the size of bumper and chassis on the MPV car. Testing simulation was performed by modelling Impactor as rigid body and crash box as flexible. Fixed support was housted in the surface of rear side of the crash box. Simulation process was started from the impactor moving to supress crash box. This Impactor collision led to deformation on the crash box. Crash box material was AA7004-T7, it was modelled as bilinier isotropic hardening. Based on the research result, the addition of pre folded pattern is able to reduce impact force at the first impact and has stable characteristic as well as predictable collapse mode.

Crash Box attached between bumper and chassis of a car serving as a kinetic energy absorber during the collision. In previous research, origami pattern crash box was tested at low speed, high speed, and frontal impact and oblique impact directions. They resulted predictable collapse and stable deformation patterns. It is directly proportional to the energy absorption during the impact. Origami pattern crash box was modeled in square but it cannot be used if it is applied in MPV car, the geometry is unsuitable to the bumper and chassis. Therefore, in this research, the crash box designed according to the size of bumper and chassis of MPV car where its shape is rectangular on the surface. This research will compare the deformation pattern between origami and rectangular crash box adapted to conditions and dimensions of the MPV car. Design built using CAD software and simulation is performed using FEM (Finite Element Method) software. Simulation test modeled with impactor, bumper and crash box, while offset frontal test with 16 km/h impact speed conducted using material bilinear isotropic hardening modeling. Result show that origami pattern crash box has predictable deformation pattern than rectangular pattern crash box.

Ballistic limit is a speed limit where projectile with a certain shape, angle of attack and size is not able to perforate a target with certain properties and thickness. This paper aims is to determine and analyze the ballistic limit of commercial medium carbon steel plate which has been hardened by induction heating by using finite element based simulation. A plate with a thickness of 8 mm was shot by a deformable blunt projectile with a diameter of 20 mm, a length of 80 mm and a mass of 0.197 kg with an angle of attack of 90° against the plate. Simulation results show that projectile with a speed of 225 m s−1 is still able to penetrate the plate in the form of plugging. The plate can withstand the projectile rate at a maximum speed of 215 m−1. At this speed, the plate is damaged but the projectile does not penetrate. The plate still has ductility properties, as during the simulation there were deflection and bulge in the back side.
