Structural testing simulator for wind turbine blades using matrix-based finite element analysis.
by Michael J. Desmond Jr.
National Wind Technology Center
BladeFS (Blade Fatigue Static) is a MATLAB® script that was developed to determine loads and deflections associated with fatigue and static structural testing of wind turbine blades using matrix based finite element analysis. Features include blade property and target test load generation functions, saddle and winch optimization routines, a simple graphical user interface, an easy to manipulate excel input file, and word and excel summary output files.
The finite element model of the wind turbine blade utilizes rigid-body, lumped mass, Timoshenko beam theory with six degrees of freedom (flapwise displacement and rotation, edgewise displacement and rotation, axial displacement, and torsion). Blade property and target test load generation functions are based on historical data from horizontal-axis, three-bladed, land-based, utility scale wind turbines with blades ranging 9 to 60 meters in length. Mode shapes and excitation frequencies are computed using Eigen analysis with a cantilever beam boundary condition (twist coupled using Euler angles).

This is the user's guide. Please refer to it when trying to understand how to run the program.
This is the self-extracting archive of the latest version of BladeFS. Simply execute it in an appropriate directory to extract the files. This archive contains the user guide, BladeFS executable, sample input files, change log, and our disclaimer.
Although the scripts were created using MATLAB® 7.6.0 (R2008a), you will need the MATLAB® Compiler Runtime (MCR) to run the BladeFS executable. The MCR is a standalone set of shared libraries that enables the execution of MATLAB® scripts on computers without an installed version of MATLAB® and associated licensing. This only needs to be installed once. MCR and BladeFS will run on only Microsoft Windows® operating systems.
