Topology Optimization of an Airplane Component to Be Made by Selective Laser Melting Technology

Abstract:

This paper presents a research performed in the field of airplane components made by Additive Manufacturing (AM) methods, such as Selective Laser Melting (SLM) technology. The mechanical behavior of fixing clamps for the hydraulic pipes that are passing through an airplane fuselage has been analyzed by using a dedicated topology optimization program. Two types of materials have been considered as an alternative for this type of component to be manufactured by SLM: Ti6Al4V and AlSi12. By using the Femap NX Nastran topology optimization program, it was possible to re-design the shape of this component and to select the best type of material that is adequate from the mechanical strength point of view, with a minimum weight as an optimization goal.
