Optimización topológica de un asiento de autobús interprovincial para el cumplimiento del reglamento ECE-R80

Abstract

The manufacturing process of the seats from the metallic body of the interprovincial buses made in the country are made by craft. The analysis of the original and optimized pieces was carried out through the following steps: with a pre-processing carrying out a CAD design in order to draw the geometry of the seat structure, then, there was a process in which a particular mesh design was developed, which allowed to lighten the results at the moment of being evaluated in the MEF programs; the efforts to which the most fundamental pieces are exposed were verified in post-processing through simulation in computer programs. The pieces that were optimized are: the seat leg, the spring support, the seat belt support plates and the elbow supports. This topological optimization in each of the pieces that are part of the interprovincial service bus seat, allowed to reduce the weight of the seats and therefore the entire body, which influences a reduction in fuel.
