The accuracy of the aerodynamic shape of the wind turbine blade directly affects the power generation effect of the wind turbine blade.It is directly related to the profile accuracy of the wind turbine blade mould.The more accurate the profile accuracy control of the wind turbine blade mould,the more accurate the aerodynamic shape of the wind turbine blade product.However,as the length of wind turbine blades continues to increase and the contours continue to be complicated,the profile accuracy of wind turbine blade mould is becoming more and more difficult to control.The accuracy of profile measurement of wind turbine blade mould is also more stringent during mould installation and commissioning.In order to improve the profile accuracy of wind turbine blade mould during installation and debugging,this paper analyzes the influencing factors of the profile measurement accuracy of the wind turbine blade mould,and focuses on the analysis of the measurement methods and data fitting methods,and summarizes the measurement methods and data fitting methods suitable for the profile measurement during the installation and debugging process of the wind turbine blade mould.At the same time,the two groups of measurement results of free state and leveling state of laser tracker are compared and analyzed,and the results show that the leveling operation of laser tracker has an intuitive effect on the measurement results.Different fitting methods are used to analyze the global measurement data,and the comparison results show that the judgment results of global measurement and relationship matching fitting data processing are the most ideal,and the data of profile control will be more accurate.The actual operation verification,through the standard measurement method and data processing method,achieves the purpose of improving the precision of the profile during the installation and debugging of the wind turbine blade mold.
