We selected material and process design, wind turbine blades, are the main factors determining the wind power device performance and power, affect the unit cost of wind power generation, in order to improve the efficiency and reduce the cost of the fan two factors, making positive development of large leaves. Generally speaking, wind blade length of a few meters, or even tens of meters, so large in size, with little or no previous measuring equipment suitable for 3D measurement can be performed on it, that is to use laser total station 3D measurement, 3D data also just get the key points, slow measurement speed and low accuracy.
1 scanning data integrity (large scale comprehensive scanning, accurate access to complete three-dimensional data)
The workpiece is often large and difficult to move as a result of energy equipment. It is difficult to obtain the complete and accurate data by using the traditional measurement method.
The 3D scanner uses a non-contact scanning mode, easy to solve the problem of data processing and extraction, 3D Huaguang through repeated practice of integrity and accuracy of the scanned data to conduct a comprehensive study and practice, summed up the technology of 3D integrated solutions, which is the large size workpiece can be complex, with output data all of the results. Scanning to cover a wide range of depth, suitable for the large depth of field objects (such as impeller) were scanned by reverse engineering can improve the blade axial load.
2 the scanning time is fast, so that the work efficiency is maximized
Using the traditional reverse equipment - three coordinate measurement of the way efficiency is low, it is often measured a larger workpiece takes a long time, affect the work efficiency of product detection. Using three-dimensional scanner (HL-3DS) to quickly capture the surface of the object data, fast scanning speed, short operating time, improve work efficiency, save working hours.
3 high precision error analysis (detection and application of wind energy)
The traditional means of detection products have been unable to meet the high precision production demand, by 3D scanner (HL-3DS) for fast 3D scanning, point cloud data to obtain high precision, high quality, combined with three-dimensional detection software professional, with the original model for comparison, color quality evaluation cloud spectrum, provide accurate data analysis report and assembly density analysis.
Provide high precision, high quality point cloud data, the scanning accuracy of 0.015mm/m. For large objects, the development of 3D Photogrammetry System Huaguang (HL-3DP), which can accurately make quality inspection of products.
