Abstract :
The paper investigates the coupling of rigid body movement and elastic vibration system. The system dynamic equations is established by Lagrange equations, the stiffness matrix and gyroscopic matrix are time-dependent which reveals the coupling relations between rigid body movement and elastic vibration. Newmark numerical integral method is used to solve the vibration differential equation of the elastic blade. It turns out that the vibration of blade can be caused by variable rotation of the disc. Matlab is used to visualize the datum by figure.
