An Innovative Approach for the Validation of Computational Structural Outcomes of Octocopter’s Connection Arms Through Advanced Finite Element Methods

Abstract Reliability testing on computational structural outcomes is necessary because they are relays approximations. This study uses the connecting arm finite element method to validate computational structural results. The connecting arm’s displacement has been predicted using ANSYS Structural 17.2, a sophisticated analysis tool. This study uses the Multirotor Unmanned Aerial Vehicle (MUAV) connecting arm as a test platform. At various working situations like heavy gust loading, low thermal conditions, etc., ANSYS Fluent 17.2 computes the aerodynamic loads on the sophisticated Octocopter’s connection arms. These conditions compute connection arm weight-related structural outcomes. Through ANSYS Structural 17.2, structural displacements have been obtained due to aerodynamic loads and/or connection arm weight. The typical numerical approach validates the displacements analytically. This novel method has increased the computational results’ credibility. The connecting arms are then computed for equivalent elastic stress, strain energy, equivalent elastic strain, and stress intensity level. This Octocopter survives agricultural, foggy, and dust spraying. The modified convergent-divergent passage-based spraying tank has been mounted to an Octocopter to project fertilizers, insecticides, and chemicals correctly on working domains. Thus, the Octocopter with a convergent-divergent passage-based spraying tank may require additional push to finish the operation. These increased thrusts directly impact propeller performance and connecting arm longevity. Thus, computational structural results of the sophisticated cantilever construction (connecting arm) for lightweight materials are essential. This computational structural simulation imposes over 25 lightweight materials. After that, connection arms for different working situations were found. The Octocopter’s propeller diameter and connection arm design relationship are also unique. Thus, this confirmed computational inquiry will help future researchers build and deploy large payload-based drone connection arms.
