Abstract
The improvement of the safety of the road bus structure against impact scenarios and reduction of the injuries and death in traffic accidents is crucial in a country with continental dimensions like Brazil, where the road transport matrix is fundamental in the traffic of people and goods. In this context in the present work is explored the possibilities of the metallic tubes filled with aluminum foam as shock absorber in the bus structures. With this goal, an experimental campaign using tubes filled with aluminum foam was made. In these tests, uniaxial compression and three points bending tests were performed. The finite element method was implemented in LS-Dyna [2] and simulations were carried out, considering material and geometric non-linearities. The material properties were calibrated using the tests cited. Then, a bus structure modeled with finite element method was modified adding metallic tubes filled with aluminum foam to improve the structure performance in rollover and semi-frontal impact scenarios. Commentaries about all the results with the bus model are finally presented.
