Nonlinear Dynamic Behaviors of a Deploying-And-Retreating Wing with Varying Velocity
In this paper, the nonlinear dynamical behaviors of deploying-and- retreating wings in supersonic airflow are investigated. A cantilever laminated composite beam, which is axially moving at a known rate, is implemented to model the deploying-and-retreating wing. Associated with Reddy's third-order theory and von Karman type equations of large deformation, the nonlinear governing equations of motion of the deploying-and-retreating wing are derived based on the Hamilton's principle. The nonlinear partial differential equations of motion are transformed into a set of the ordinary differential equations using Galerkin's method. The nonlinear dynamical behaviors of the deployable-and- retreating wing are investigated in the cases of three different axially moving rates during deploying process and retreating process using the numerical simulations. © 2013 Elsevier Ltd.
