Designing, Modelling, and Structural Analysis of Quadrotor UAV Frame

Demand for unmanned aerial vehicles (UAVs) has been increasing day by day due to their numerous advantages such as their mechanical simplicity, cheaper, durability, and ease of control as compared to helicopters. Based on a wide range of applications, the size and shape of UAVs vary depending on their load capacity and endurance limit. An unmanned aerial vehicle is an electromechanical device with six degrees of freedom (DOF). In this research work, design, modelling, and analysis of fixed-arm quadrotor UAVs were performed to understand the mechanism of its rigid body’s movements. Total deformation and equivalent stresses in ANSYS simulation were calculated to assess structural integrity, performance, and material safety under applied loads. A 3D model of a fixed-arm quadrotor frame was created in SolidWorks® 2021 and then imported into ANSYS® 2022 R1 for analysis.
