Static Test and Analysis for Wind Turbine Blades

The deformation characteristic of the wind turbine blade under load is tested by the rig for testing dynamic characteristics of wind turbine blades. Several groups of experiments are made by changing the load and load location, and the bending moment of each section is calculated. The key strength-bearing parts of the wind turbine blade are identified through experiments and finite element static analysis to provide references to the design and manufacture of the wind turbine blade. The study as presented in this paper is of great significance to improvement of the overall performance and the optimization design of the wind turbine blade.
