Abstract

Abstract

In view of the extensive application of curved fiber composite laminates in the lightweight design of high-speed train structures, the aeroelastic stability of elastic and viscoelastic variable-stiffness composite panels in a subsonic flow field was studied. First, classical thick theory along with a Mindlin plate was adopted for structural modeling and potential flow theory for aerodynamic modeling. An aeroelastic model of composite variable-stiffness panels with curvilinear fibers was then established adopting the principle of virtual work and the finite element method, which was solved using complex mode theory in the frequency domain. The divergence characteristics for key parameters were investigated following verification of the validity and convergence of the presented method. Numerical results show that, relative to the straight-fiber panel, the critical divergence speed can be increased by approximately 50% by varying the path orientations of the curvilinear fibers.
