Abstract
In this proposed work we intend to develop a methodology to assess the bus truck structure behavior when submitted to frontal crash using the simplified model of the truck and Genetic Algorithm. The simplified model consists of a set of flexible or rigid bars linked with non linear spherical and translational joints. The adjustment of the non linear joints is carried out by means of Shell Finite Element Model, Experimental Test or Analytical Expressions. Using this tool was possible to study different project alternatives to improve the performance of the truck structure of interurban busses when submitted to frontal crash.
