Abstract
A study proposes some improvements based on the recursive radial basis function (RRBF) network model, while permitting relatively accurate limit-cycle oscillation (LCO) predictions after structural parameters change. The new reduced-order model (ROM) is named the POD-RBF network. The constructed POD-RBFnetwork is applied to predict the unsteady aerodynamic forces of a NACA 64A010 airfoil. After coupling with the structural equations of motion, the LCO trends and bifurcation point under different structural parameters can be predicted within a fraction of the time.
