Abstract EN
This paper focuses on the derivation of the aerodynamic force for the cantilever plate in subsonic flow.
For the first time, a new analytical expression of the quasi-steady aerodynamic force related to the velocity and the deformation for the high-aspect-ratio cantilever plate in subsonic flow is derived by utilizing the subsonic thin airfoil theory and Kutta-Joukowski theory.
Results show that aerodynamic force distribution obtained theoretically is consistent with that calculated by ANSYS FLUENT.
Based on the first-order shear deformation and von Karman nonlinear geometric relationship, nonlinear partial differential dynamical equations of the high-aspect-ratio plate subjected to the aerodynamic force are established by using Hamilton’s principle.
Galerkin approach is applied to discretize the governing equations to ordinary differential equations.
Numerical simulation is utilized to investigate the relation between the critical flutter velocity and some parameters of the system.
Results show that when the inflow velocity reaches the critical value, limit cycle oscillation occurs.
The aspect ratio, the thickness, and the air damping have significant impact on the critical flutter velocity of the thin plate.
