Numerical modal analysis of DTU 10-MW reference wind turbine’s blade using modified Myklestad´s method

Since the rotor blade system of an horizontal axis wind turbine is responsible for converting energy into mechanical, which turns electrical and predicting its dynamic behavior vital importance. In that sense, this paper deals with performing a modal analysis belonging to DTU 10-MW reference by using modified Myklestad’s method. The model was built on two different keystones, as follows: first, considering uncoupled bending in out-of-plane (flapwise) in-plane (edgewise) directions coupled bending-torsion motion also both directions. order accomplish these objectives, Python code implemented. computed eigenfrequencies were compared results obtained finite element Besides, mode shapes plotted centrifugal stiffening taken account. Results suggest feasibility method purposes, since good agreement data achieved has considerably less complex implementation than
