Design and application of stop-lossing tool for wind turbine main shaft
In order to avoid safety accidents such as impeller fall and tower sweeping caused by shaft fracture of wind turbine,a set of main shaft stop-lossing tool was designed.3D software was used to establish the main component model.Finite element simulation analysis software was used to evaluate the tool load while main shaft fractured.The impact of the tool installation on the wind turbine was calculated using structural mechanics.The results showed that the stress of the clamping plate,clamping block,clamping ring,and other parts of the tool didn't reach the yield strength,as well as the stress of the engine bed board.Plastic deformation didn't occur.The tool structure met the design requirements and didn't have any other safety impact on the wind turbine.At present,the designed and developed tool have been applied in more than 150 wind turbines of a foreign brand,effectively reducing the risk of wind turbine safety accident.
