Abstract
The main objective of the presented research consists in the redesign of an airplane component to decrease its weight, without affecting the mechanical behaviour of the component, at the end. Femap NX Nastran and ANSYS FEA programs were used for the shape optimization and for the estimation of the mechanical behaviour of a fixing clamp that was used to sustain the hydraulic pipes that are passing through an airplane fuselage, taking into consideration two types of raw materials – Ti6Al4V and AlSi12 powder from which this component could be manufactured by using the selective laser melting (SLM) technology. Based on the obtained results, the airplane component was finally manufactured from titanium alloy using the SLM 250 HL equipment that is available at SLM Solutions GmbH company from Luebeck, in Germany.
Highlights
Airplane industry is one of the most spectacular fields of research regarding the Selective Laser Melting (SLM) technology
Shape optimization and FEA programs are often used in order to estimate the mechanical behaviour of different type of airplane components made by SLM technology [6,7,8,9]
The research performed by the authors in this field of research was mainly focused on the possibility of redesigning of an airplane component - the fixing clamp used for sustaining the hydraulic pipes that are passing through an airplane fuselage, in such way that the weight will be significantly decreased, without affecting the mechanical behaviour of the component, at the end
Summary
Airplane industry is one of the most spectacular fields of research regarding the Selective Laser Melting (SLM) technology. The mechanical behaviour of the airplane components produced from different type of materials was one of the most important researches developed in this field by different researchers in the world [4,5]. Shape optimization and FEA programs are often used in order to estimate the mechanical behaviour of different type of airplane components made by SLM technology [6,7,8,9]. Based on the obtained results, the fixing clamp was manufactured from Ti6Al4V material by selective laser melting technology at SLM Solutions GmbH company from Luebeck, Germany, at the end
