摘要
The CFD/CSD coupling method is turning into the main research direction for the static/dynamic aeroelastic analyses.If one wants to use the method for the complex engineering aeroelastic problems,he needs to investigate the relative aeroelastic algorithms,such as the numerical computational method of unsteady aerodynamic forces,equivalent low-dimensional structural finite element model and the solution method of structural dynamic equations,data transfer technique between fluid and structure,the moving grid method,etc.Besides,he also needs to improve the computational efficiency by such as massive parallel CFD algorithm,reduced-order model(ROM) of unsteady aerodynamic forces,etc.In this paper,based on the authors' recent investigations,the research progresses in computational aeroelastic methods and their applications to engineering problem are summarized.
