    Abstract
  • The influence of the shroud's radial position on the vibration characteristics of the fan blade considering its dynamics design requirements was investigated. Mechanical model of the shrouded fan blade was built based on beam theory, and the first order natural frequency was obtained using Rayleigh method. Further the influence of the shroud's radial position on the first order natural frequency was also acquired. The influence of the shroud's radial position on the contact status and vibration characteristics was also investigated by the nonlinear finite element method with contact elements. The results reveal that the stiffness and the first order natural frequency are maximal while the relative shroud's radial position is 0.75. The vibration characteristics for multi-modes are best while the relative shroud's radial position is 0.55-0.68. The pressure of the contact surface of the shroud decreases for the increasing of the relative shroud's radial position, and the tangential contact stiffness first increases and then decreases for the increasing of the shroud's radial position.
