Design and optimisation of a tipping silo semi-trailer by using innovative materials

This research reports the results of implementation of composite materials and the complete redesign of a tipping silo semi-trailer. The conventional semi-trailer, used for comparison, was designed based on a Feldbinder commercial model, while the innovative one has the same overall dimensions but a new geometry, while maintaining the same performance in terms of deflection and safety factor. The research involves sizing and verification of the results obtained using finite element software (Solidworks Simulation®) with different loading conditions. The main result is that the optimised solution has the lowest weight, with a reduction of about 28 % considering the same equipment and accessories mounted on the two solutions. The last part of the research concerns an estimate of economic investment containing the return on the initial investment and the reduction in fuel consumption by comparing the two solutions. Considering that the vehicle always carries the maximum (payload = 27,500 kg) and the overall weight reduction of about 1800 kg, there is a reduction in fuel consumption for the proposed solution. The return on investment for the new solution occurs between three/four years depending on the number of kilometres driven annually. Finally, the purpose of this paper is to create an example of a procedure for reducing the carbon footprint and the fuel consumption of vehicles by replace and redesign entire mechanical components, in this case industrial vehicles, that would be useful to follow and replicate for any specific case study and increase the eco-sustainability of industrial manufacturers.
