Forecast on structural behaviour for a composite city bus in GRFP

A self-supporting city bus structure, conceived and produced in glass fibre reinforced plastic with modular composition criteria, was analysed in the static and dynamic field. The analysis was performed using finite element models using two different models that can be improved for further studies in connection with the development of the design to a final form. The structural behaviour trends have been found both by analysing the static load bearing conditions considered as extreme, as well as obtaining the most significant vibration shapes. In this way improvements of the examined prototype have been obtained.
