ANALYSIS of INTERNAL COMBUSTION ENGINE COMPONENTS TO BE DESIGNED and PRODUCED by ADDITIVE MANUFACTURING (AM)
Research Groups 20-Progettazione meccanica di motopropulsori e componenti motore
Thesis type NUMERICAL AND DESIGN ORIENTED
Description AM involves the development of objects with complex 3D geometry, stacking the constituent material layer by layer. Initially it used plastics, resins and composite materials, but with laser fusion it can also work metals of interest of automotive and aerospace industries. Currently aluminum, thanks to its high strength/weight ratio, is second to steel in automotive sector and the development of AM aluminum alloy engine components has become very interesting, as the integration between CAD/CAE and AM that allows to produce components with less design restrictions, than those that bind more traditional production processes, optimizing their geometry.
AM design of engine components such as cylinder head, crankcase and exhaust manifold, but not only, constitutes an innovative field of research as regards the possibility of optimizing the geometry and the cooling and heat exchange circuit with the aim of:
- Level the temperature range to avoid strong thermal gradients and consequent structural damage;
- Increase the cooling capacity with a uniform distribution of the flow without the formation of local zones with low refrigerant circulation speed;
- Reduce the pressure drop of the cooling circuit.
The thesis will be focused on the design of an engine component (to be defined in collaboration with interested companies) using the AM technique. The activity includes:
- Design of the component;
- CFD optimization of cooling and/or heat exchange to demonstrate the benefit of the AM process;
- FE analysis to demonstrate the feasibility of the AM process.
