Crash Box is a very important part as absorbing impact energy, especially in the frontal crash case. The purpose of this study was to determine the optimal design on two circular cross sections Crash Box to its ability to absorb impact energy and deformation pattern. The independent variable in this study were length, and thickness of the Crash Box with length of tube 1 (h ) = length of tube 2 (h 2 ) = 40, 50, 60 mm and thickness of tube 1 (t 201 1 1 ) = thickness of tube 2 (t ) = 2,5 ; 3 ; 3.5 mm were analyzed by the Taguchi method.The dependent variable is the energy absorbed and the deformation that occurs in Crash Box due to the impact test (Impactor) and is measured by using finite element-based software which is Ansys 14.5. Based on data from the simulation results, it can be obtained on one circular cross section Crash Box has the ability to absorb the energy of 2762.89 A. For optimum design of two circular cross sections Crash Box has the ability to absorb the energy of 4435.04 J. Optimum design of Crash Box has length of tube 1 (h 1 ) = 40 mm, length of tube 2 (h 2 ) = 60 mm, thickness of tube 1 (t ) = 3.5 mm, thickness of tube 2 (t ) = 3 mm. From the deformation pattern analysis, it can be seen that the deformation in the Crash Box can be divided into 2 types: Concertina mode (bending on the Crash Box walls is symmetric) and Diamond Fashion (bending on the Crash Box walls is not symmetrical).Keywords: Crash Box, Simulation, Energy, Deformation, Sectional Shape, Buckling.
