MODSIM 3DXCONFERENCE Lightweight Engineering
Hello everyone! I am pleased to invite you to assist my presentation in the Global 3DEXPERIENCE Modeling & Simulation Virtual Conference, on November 17-18, 2020.
My presentation:
In order for a quadcopter to be able to perform a mission, his structure must support the loads of the mission's activities. However, a heavy structure directly impacts the performance of this aircraft. In this way, this article aims to execute a structural design for a remotely piloted aircraft using modern mass reduction and manufacturing techniques such as topological optimization and additive manufacturing. The proposed quadcopter must support the mass of all components, loadings imposed by the motor thrust and a camera as a payload with a 150 gram. Thus, the first step performed was the requirements analysis to determine what is necessary for the execution of the proposed mission, this step allowed to select all the components that make up the aircraft and, therefore, start to create the CAD nominal model. Subsequently, the initial structural design was performed using the finite element method. The first structural calculations aimed to validate the nominal geometry in relation to the loading conditions imposed by the motor thrust. The initial structural validation allowed to proceed with the topological optimization of the aircraft component directly responsible for engine loading. The objective function imposed was to minimize the mass and the restriction of 1.2 times the nominal displacement. The optimized model was manufactured via additive manufacturing and, as a result, a total mass of 36 g was obtained, ie the component mass was reduced by 45.5% what results in a reduction by 75% of safety coefficient. Therefore, the topological optimization and additive manufacturing allowed to manufacture a new structural with lower mass.
