The Challenge
SOGECLAIR aerospace, a major partner in engineering and prime contractor for the aerospace industry, was tasked with the development of a new flooring concept for aircraft cabins. The challenge was to create a lighter structure, adjustable panels for all types of aircraft, and ensure easier installation and maintenance. The aerospace industry has always been at the forefront of weight optimization and lightweight design, hence it was not surprising that aerospace also was one of the first industries to use alternative materials such as composites. The engineers had to consider conflicting issues such as weight, design, maximal dimensions, strength, stiffness etc. The use of optimization technology is the solution to combine all of these constrains with respect to an optimal composite layout. In this context SOGECLAIR aerospace investigates innovative materials and processes to integrate them in the design, analysis, and optimization.
The Solution
To address these challenges, SOGECLAIR aerospace employed Altair's HyperWorks suite, particularly HyperMesh and HyperView as a pre- and postprocessor, OptiStruct for optimization issues, RADIOSS for linear and nonlinear simulation, and solidThinking Evolve/Inspire for concept modeling. In a typical project, the first step is a feasibility study of the objectives to clear up whether it is possible to create an efficient solution. To develop composite structures, the engineers conduct Freesize and Size optimizations defining different patches and layer thicknesses of the composite material, followed by a shuffle optimization to determine the optimal stacking sequence of the single layers. Also gauge optimizations are conducted in order to reach the optimal dimensions of the composite stiffener. In the subsequent development process, the engineers compare the numerical analysis results with tests data, in particular the strains in different stackings.
