In this paper, Newtonian method is adopted to establish the lateral vibration of the axial movement of the beam vibration differential equations. Discrete equations of motion Galerkin process is also applied to the mechanical modeling study of high-dimensional rotating flexible Euler beam and the dynamic response of the problem. Then, the paper analyzes the impact of the rotation angular velocity of the rotor radius and rotating beam on the rotating beam dynamic response. With the aid of its modal function, five modes of vibration of a rotary beam are therefore drawn.
