Abstract


  • This paper presents a dynamic response analysis of the blade of horizontal axis wind

    turbines using finite element method. The blade is treated as a cantilever and modeled with

    two-node beam element. The blade element–momentum theory is applied to calculate the

    aerodynamic loads. Dynamic inflow and dynamic stall are taken into account to reflect the

    transient aerodynamics. The centrifugal stiffening is introduced to consider the restoring

    effects of centrifugal force. An aerodynamic damping model is presented for calculating the

    overall damping ratio instantaneously during time-domain simulation. The structural

    dynamic equation is solved using Newmark method and the overall dynamic response of the

    blade is obtained based on the modal superposition principle. Applying the proposed

    method, the power production load case of a 1.0 MW wind turbine operating in turbulent

    wind field is simulated. The simulation results indicate that the blades of large-scale

    horizontal axis wind turbines undergo significant vibration and deflection during operation,

    and the centrifugal stiffening and aerodynamic damping both considerably affect the

    structural response of the blade.
