  • The forced response characteristic of bladed disk under fluid excitation with aerodynamic mistuning was analyzed.The resonant criterion of bladed disk and the aerodynamic mistuning theory were performed first.Then, the modal reduction theory and the precise integration method were given.Finally, the transient response characteristics of bladed disk under tuned and mistuned fluid excitations were investigated.In this section,the system mass,stiffness and damping matrix were obtained by FEM(finite element method),and MATLAB code was then used to study the response characteristic.
