In This paper, a single objective optimization based on response surface methode is adopted in order to calculate the optimalexpansion tubeaxial splitting model parameter. Expansion tube-axial splitting as impact energy absorber applied to overcome collision accidents on passenger trains. Impact energy absorber will absorb the energy that occurs during an accident, so passengers are safe. The dimensions of the expansion tube axial splitting module are influenced by several parameters including tube tickness (t), Inner diameter of tube (D1) and outer diameter of Dies (D2). That are influential with the total energy absorbed by the impact absorbing module. Formulations that have been obtained in previous studies are optimized to get the best dimensions. This study resulted in the selection and optimization method of the design of the impact absorbent module that fits the parameters of the impact absorbent module from various module geometry alternatives taking into account the availability of space.
