| Abstract: | The coupling vibration frequency equations of the helicopter rotor blade are formulated by means of the finite element method. A direct algorithm method for the generalized feature value of the coupling vibration is presented, by which the calculation and the convergence of the generalized feature value are effectively resolved. |
