Topology Optimization Design of Typical Hinge for Civil Aircraft

摘要

The rapid development of the additive manufacturing technology (3D printing) has brought much greater optimization space for the structural innovation design. The combination of topology optimization design and additive manufacturing technology can further reduce the structural weight, thus improving the bearing efficiency of the structure. The main purpose of this paper is to explore the feasibility of reducing weight for civil aircraft structure by means of optimization design. The structural topology optimization design of typical hinge structure for civil aircraft is carried out. Compared with the traditional structure, the topology optimization structure achieves a weight reduction of 25% and a structural stiffness increasing of 75.7% under the condition that the strength requirement is satisfied, which reaches the expected goals.
