Análise estrutural em carroceria de ônibus com redução de massa

Abstract

The present work had as its objective to analyze, with a focus on total mass reduction, the design of a structural bus cocoon, having as direction, thickness reduction and exchange of materials. The finite element analysis method was used as a basis, with the help of Altair's Hypermesh software, in order to highlight the main regions to be conceptualized in order to reduce the total mass, while guaranteeing equivalent structural function. Thickness and material optimization proposals, in relation to the current concept, were created in SolidWorks 2021 software and then numerically simulated for validation. The bus body analysis was validated based on the indication of permissible stress based on yielding, which was approved because the maximum equivalent stress was less than or equal to the permissible equivalent stress considered for each material used, as provided for in the internal validation regulations, considering its own weight, body torsion, curve and braking.
