The design and research of large-scale wind turbine blades automatic generation system

摘要

In the large-scale wind turbine designed, a large proportion of work occupy in the blade design, but because of three-dimensional blades model design difficult to achieve, and through the reverse way to reconstruct spending is large and modifying accordingly, which limit the statics, fatigue and other follow-up analysis about virtual prototype greatly. To this end, by studying the leaf design theory which is used widely today and with the virtual prototype parametric design methods, research and design a set of blade design system, respectively, from the blade radius, chord length, pitch angle and the thickness chord ratio of four degrees of freedom to change the blade design parameters, the free way of three-dimensional design model of leaf to make the design more perfect, fast, flexible, providing strong support for follow-up analysis.
