Abstract:

Modern aircraft components need structural integrity and operating reliability for flying safety, maintenance efficiency, and service life. Computational engineering enables multiphysics finite element simulation to evaluate structural performance under representative operating conditions before building a physical prototype. An integrated Finite Element Analysis (FEA) simulation framework offers multiphysics modelling and structural evaluation of an aircraft component. Static, modal, thermo-structural, and fatigue analyses examine mechanical response, dynamic stability, thermal effects, and long-term durability. Static analysis calculates stress distribution, deformation, and structural safety under loads, while modal analysis determines natural frequencies and dynamic vibration characteristics. Thermo-structural analysis determines how temperature variations affect stress generation and dimensional stability, while fatigue analysis forecasts service life under cyclic loading and identifies damage-accumulation locations. The structures are safe, as the numerical results show that the expected equivalent stresses remain within the material's strength limit. The dynamic study indicates steady vibration without critical resonances, and the thermo-structural analysis shows acceptable thermal deformations and stresses. Fatigue projections indicate long-term operating fatigue life. The proposed multiphysics finite element framework is an efficient, reliable structural assessment method that ensures the safety, durability, and reliability of advanced aerospace components and optimises design while reducing development time and cost.
