RISAn Improved Decoupled Finite Element Analysis Method of Ultra-Large Offshore Wind Turbine Subjected to Combined Wind–Wave Actions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Owing to the simplification of the wind turbine, it is difficult to accurately simulate the interaction between the rotor system and the supporting structure using the decoupling finite element method. Therefore, when using ...
Investigation of Sensitivity Analysis of Crucial Dynamic Characteristics of Offshore Wind Turbine Utilizing Polynomial Chaos Expansion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The probabilistic-based design method is gaining attention in designing offshore wind turbines (OWTs) owing to its economic design. However, the numerous uncertain design variables and the tiny target annual failure ...
Model Test and Numerical Analysis of a Multi-Pile Offshore Wind Turbine Under Seismic, Wind, Wave, and Current Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Offshore wind turbines (OWTs) might be subjected to seismic loads with different peak accelerations during operation in the actively seismic regions. The earthquakes might be a potential risk for the OWTs due to its ...
Numerical Study on the Multifield Mathematical Coupled Model of Hydraulic-Thermal-Salt-Mechanical in Saturated Freezing Saline Soil
Publisher: American Society of Civil Engineers
Abstract: Freezing in saturated saline soil is a dynamic, coupled hydraulic-thermal-salt-mechanical (HSTM) process. The aim of this paper is to establish a model to describe the coupling process. In the model, mass conservation law, ...
Structural Control of an Ultra-Large Semi-Submersible Floating Offshore Wind Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A braceless semi-submersible floating platform is proposed for a Technical University of Denmark (DTU) 10-MW wind turbine at moderate water depths with reference to an existing National Renewable Energy Laboratory (NREL) ...
