Probabilistic optimization of Mg-based composite aircraft frame- a topological analysis

In this study, the weight of an aircraft frame structure is optimized by using a variable density method (VDM). For this, a probabilistic Mg-based composite aircraft frame model is designed in Ansys software and its multiple iterations have been performed by using its topological properties. However, these properties are established based on Lagrange function and interpolation method. Through, its multiple iterations, a numerical model is evaluated which depicts an optimized topological frame structure. The optimized structure illustrates a significant reduction in density and weight percentage of Mg-based aircraft frame as compared to domestic aircraft frame. (C) 2020 Elsevier Ltd.

Automated summary

In this study, the weight of an aircraft frame structure is optimized using a variable density method. A probabilistic Mg-based composite aircraft frame model is designed and iterated in Ansys software based on its topological properties, resulting in a significantly reduced density and weight percentage. The optimized structure demonstrates a decrease in both density and weight compared to domestic aircraft frames.
