“…Weigang and Weiji [4] thought if posterior preference optimization algorithm was used to solve this problem, the huge time consumption would be unacceptable in engineering practice due to the large amount of evaluation needed for the algorithm. So, a new interactive optimization algorithm, i.e., interactive multiobjective particle swarm optimization (IMOPSO), was presented in their work.…”

An optimization technique called shape-linked optimization, which is different from the traditional optimization method, is introduced in this paper. The research introduces an updated wing optimization design in an effort to adapt to continuous structure changes and shapes while optimizing for a lighter weight of the structure. The changing tendencies of the thickness of wing skins and the cross-section areas of the wing beams are fitted to continuous polynomial functions, whose coefficients are designed as variables, which is a different engineering approach from the size variants of the thickness and the area in the traditional optimization. The structural strength, stiffness, and stability are constraints. Firstly, this research unearths the significance of utilizing a modernized optimization process which alters the production of the traditional 12 or over 12 segment wing design and applies new approaches and methods with less variables that contribute to expedited design cycles, decreased engineering and manufacturing expenditures, and a lighter weight aircraft with lower operating costs than the traditional design for the operators. And then, this paper exemplifies and illustrates the validity of the above claims in a detailed and systematic approach by comparing traditional and modernized optimization applications with a two-beam wing. Finally, this paper also proves that the new optimized structure parameters are easier than the size optimization to process and manufacture.

“…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]. 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.…”

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.

“…There are specialized computer programs that are available and could be used for these purposes, such as HyperWorks, Tosca or Femap NX Nastran. Such types of programs are based on the finite element method and are widely used by different researchers in the world for optimizing the shape of different types of car or airplane components [12,13]. The presented work investigates the possibility of decreasing the weight of fixing clamps for the hydraulic pipes that pass through an airplane fuselage, without affecting the mechanical strength of the component.…”

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.
