Development of Reduced Order Models to Non-modeled Regions,ions where a neutral axis would exist. These simplistic beam models can be desirable for analyses such as flutter where computation is intensive for structures such as fuselage, aircraft wings, wind turbine blades, etc.

Body Wise Time Integration of Multi Body Dynamic Systems,es are updated and the inner loop is executed once again until the error of the constraints is negligible. It turns out, that the constraints can be updated separately as well, which can be used again for parallel computing. In the paper, the theory will be outlined and implemented using an N body p

Static Calibration of Microelectromechanical Systems (MEMS) Accelerometers for In-Situ Wind Turbinesets from results. The objective is to enable easier comparison of results obtained from multiple accelerometers positioned arbitrarily along the blade, independent of the accelerometer orientation on the usually curved wind turbine blade surface.

Predicting Full-Field Strain on a Wind Turbine for Arbitrary Excitation Using Displacements of Optint at the optical targets was expanded using a modal expansion algorithm. The expanded displacement was used in conjunction with a finite element model of the turbine to extract dynamic strain throughout the entire structure. The results from the technique were compared to instrumented strain gages

Predicting the Vibration Response in Subcomponent Testing of Wind Turbine Blades,mponents to the full-scale plate. The effect of the ply stack up scheme and size of the subcomponents in predicting accuracy of the scaling laws are then investigated by applying partial and complete similarity conditions. According to the results, subcomponents with modified ply stack up could be f

Linear Modal Analysis of a Horizontal-Axis Wind Turbine Blade,e shapes are found to be combinations of the in-plane and out-of-plane bending. The results of the modal analysis are compared with results from a finite element analysis, and the mode shapes and frequencies are consistent. The method is also applied to NREL’s 5 MW wind turbine blade to find its ben

Reduced-Order Modeling of Turbine Bladed Discs by 1D Elements,l cross sections. The shape functions are based on the exact solution of the beam equation to avoid shear-locking. Torsional stiffness includes the effect of warping. The proposed model is compared with accurate 3D FE models in terms of modal properties. Blades of different shape and slenderness tak
