Design and Analysis of a Novel Multirotor Structure Using Generative Design and Finite Element Analysis

The rapid advancement of unmanned aerial vehicles (UAVs) has increased the demand for efficient and reliable multirotor structure designs. This paper proposes a comprehensive approach to designing and analyzing a new multirotor structure by combining Generative design (GD) techniques and finite element analysis (FEA). Integrating these methodologies aims to enhance UAVs' structural integrity, performance, and manufacturability. The proposed method first uses GD to generate a new configuration octocopter that meets the design requirements, which include the initial CAD model, selection of the preserve geometry and obstacle geometry, specification of the material and manufacturing method, selection of the structural constraints and loads, and the FEA is then used to evaluate the structural performance of the model outcome and current commercial configurations. The results show a reduction in the weight of a new configuration octocopter by 12.259%, without compromising the strength of the structure as shown in FEA results
