机翼长桁数字孪生模型构建及可视化研究OA

The strength and fatigue tests of the wing lower panels ensure the safety of the aircraft during flight.However,there are issues in the tests,such as the inability to accurately determine the performance of the wing lower panels and the measurement of mechanical parameters at the hole edges in regions with holes.This paper investigates the construction and visualization methods of a digital twin model of the wing lower wall panel truss structure.Firstly,the mechanical mechanism analysis and finite element numerical simulation of the section with holes in the truss were conducted,and the mechanism model and finite element model of the section with holes in the truss were established;Combining response surface optimization method to reduce the mesh order of the finite element model,a reduced order model was obtained;Subsequently,simulation data from various operating conditions were used as the training dataset for the data model,and a digital twin model of the long truss with holes was constructed.Finally,Unity game development software was used as the digital twin engine to build a digital twin model visualization platform,which realized the stress field,strain field,and structural deformation of the long truss with holes under virtual loading conditions.
