| Abstract: | Dynamic differential equation of plate - blade on the basis of discretization was established in this paper. The equation includes peg- top matrix, and both peg- top matrix and stiffness matrix change with time. The method of state - space transfer matrix was used to analyze the stability of the blade. In the end, the paper solved the stability of the equation by numerical emulation. |
