Abstract

Trains as a means of mass transportation should protect passengers against potential accidents. To reduce the risk of train accidents due to collisions, train manufacturers should implement a passive safety system. The passive safety system could be in the form of an impact-absorbing module that is used to absorb impact energy during a collision and to minimize the damage of vehicle structures in the passenger area. This study uses a module with a circular, hexagonal, and square cross-sectional shape mounted on the front end of the medium-speed train. Finite element simulations were carried out based on the standards of SNI 8826 and EN 15227. The materials used are aluminum 6005A, mild steel AISI 1018, and glass laminated with polyvinyl butyral (PVB), which are defined as bilinear elastic–plastic for the material properties and as Johnson–Cook model for the material behaviors. The numerical simulation indicated that the module with a circular cross-section has good energy kinetic absorption and fulfills the safety requirement according to the standards for the collision under speed of 45 km/h. Besides, the square cross-section can be used as a protective frame due to lower axial deformation.
