| Abstract: | An flexible beam system with three turning axles composed of two-link arm and threejoint is studied in this paper.An evolution equation corresponding to the beam system formulated by partial differential equations with initial and boundary conditions is established in an appropriate Hilbert space.The spectral analysis and semigroup generation of the operator of the beam system are discussed.Finally,a result of exponential stability of the beam system is proposed and proved in terms of semigroup properties of the system operator. |
