          Three-Dimensional Inspection of Blade Mould for Super Large Wind Power Generation

          Three-dimensional Inspection of Wind Turbine Blade Mould

          A well-known wind power equipment manufacturer needs to carry out three-dimensional measurement of wind turbine blade mold to check whether the production of blade mold is qualified. Wind turbine blade is the most basic and key component of wind turbine. Its design directly affects the conversion efficiency of wind energy and its annual power generation. Good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. Therefore, whether the quality of wind turbine blade dies can meet the standards is particularly important.

          Practical problems

          1. Because of the huge size of the wind turbine blade die (about 20 meters long and 2-3 meters wide), the surface precision is required to be high and it is inconvenient to move. When measuring with a photographic three-dimensional scanner, the cumulative error will be too large. How to eliminate the influence caused by the error is the biggest problem facing us.

          The traditional measurement method is not only time-consuming, but also limited and can not accurately measure the three-dimensional data of wind turbine blade surface, and can not complete scanning and data mosaic. It can not complete the quality inspection of wind turbine blade mould.

          Hualang solutions

          In view of the large scanning area and high surface accuracy of the wind turbine blade die, in order to eliminate the accumulated scanning error and complete splicing, Hualang three-dimensional technical engineer proposed a solution: using HL-3DP, a three-dimensional photogrammetry system, can complete the three-dimensional inspection of the super-gale power blade die without the aid of a three-dimensional scanner alone, and quickly obtain the three-dimensional precision of the blade die. Dimensional data + reverse design software (transforming point cloud data of wind turbine blade die into triangular mesh surface data)+imported into design software for post-processing, and got the detection and analysis report.
