The combined expansion tube-axial splitting of deformable rigid tube developed as new mechanism as impact energy absorber. The impact absorbing structure consists of two circular tube forming dies, each die allowing the tube to expand and to split. The latter is used to meant move away radially the debris after expansion and splitting, so that the absorption process can continue without being obstructed by the debris itself. This combination expansion tube-axial splitting module produces absorption impact characteristics wherein the absorption of the second force of the impact absorbing module is more stable. Enhancement on pipe thickness will cause force enhancement that is able to be absorbed by module. The impact energy absorber (IEA) module is one of the most important components in the application of crashworthiness technology to improve the safety of transportation facilities. The effect of impact energy absorber, the impact energy and impact force which passed to the main structure of the vehicle will be limited during a collision, so the impact of collision on passengers or cargo can be minimized. In its application, the IEA requires a very important component, which is an impact energy absorbing module. 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.
