Structural Dynamics Analysis and Model Validation of Wind Turbine Structures

https://www.osti.gov/servlets/purl/1142154

Structural Dynamics Analysis and Model Validation of Wind Turbine Structures D. Todd Griffith* Sandia National Laboratories†, Albuquerque, New Mexico 87185 The focus of this paper is the development of validated structural models of wind turbine structures and their substructures. A typical modern wind turbine is a large structure composed of a single tower, a nacelle located atop the tower which houses the drive train mechanical components, and three rotor blades. In very broad terms, a wind turbine design team must consider the dynamic response of the full system in the design process along with detailed design for each individual substructure. Blades are a critical substructure of a wind turbine as they carry large loads in capturing the energy from the wind, and must be designed to maximize performance and reliability while minimizing their cost. First, we discuss the structural dynamics analyses that are performed to design a modern wind turbine structure. Results from recent tests and validation of models for these blades will be presented.

[PDF] FINITE ELEMENT ANALYSIS OF HORIZONTAL AXIS WIND ...

https://upcommons.upc.edu/bitstreams/54844f41-77c7-4a1f-94b7-c5f9604331ca/dow…

This paper presents an aeroelastic formulation based on the Finite Element Method (FEM) to predict the performance of an isolated horizontal axis wind turbine. Hamilton’s principle is applied to derive the equations of blade(s) aeroelasticity, based on a nonlinear beam model coupled with Beddoes-Leishman unsteady sectional aerodynamics. A devoted fifteen-degrees of freedom finite element, able to accurately model the kinematics and elastic behavior of rotating blades, is introduced and the spatial discretization of the aeroelastic equations is carried-out yielding a set of coupled nonlinear ordinary differential equations that are then solved by a time-marching algorithm. The proposed formulation may be enhanced to face the analysis of advanced blade shapes, including the presence of the tower, and represents the first step of an ongoing activity on wind energy based on a FEM approach. Due to similarities between wind turbine and helicopter rotor blades aeroelasticity, validation results firstly concern with the aeroelastic response of a helicopter rotor in hovering.

Exploring the Relationship between Preprocessing and Hyperparameter Tuning for Vibration-Based Machine Fault Diagnosis Using CNNs. Previous Article in Special Issue. Combining Computational Fluid Dynamics and Gradient Boosting Regressor for Predicting Force Distribution on Horizontal Axis Wind Turbine. No special permission is required to reuse all or part of the article published by MDPI, including figures and tables. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. The article is devoted to the practical problem of computer simulation of the dynamic behaviour of horizontal axis wind turbine composite rotor blades. For this purpose, in this paper the mechanical model of a rotor blade with a composite skin possessing a stiffener was developed and implemented as a finite element model in ABAQUS. The response of the system subjected to a uniform underneath pressure was studied, and the root reaction force and blade tip displacement time histories were obtained from the numerical calculations conducted.
