Large-scale Wind Turbine Impeller Blades Reverse Remodeling And Dynamic Analysis

In this paper, from the Natural Science Foundation research project, thesis on the current model of wind turbine blades to obtain, simulation and data analysis carried out in-depth research. First of all, through the slicing blade for scanning, alignment, such as orders, access to the entire blade point cloud data, the use of reverse remodeling software Imageware, wind turbine blades for re-constituted entity. The use of shell commands skin leaves. Environment in the UG framework for the establishment of the internal structure of leaves, leaves sum to be true three-dimensional solid model. And then proceed to the analysis of the vibration frequency response function of the image. Ansys software also makes use of the wind field simulation of the flow line to determine the wind speed under different pressure and output torque with the leaf surface roughness and wind speed affect the relationship between the map. And leaves the system so the fatigue evaluation. For future improvements in blade design and provides a basis.In this paper, studies have shown that the use of virtual prototyping technology and finite element software workbench technology, can greatly increase the design efficiency, reduce physical prototypes and the manufacturing costs of destruction, the study allows us to have good practical value.
