Adaptive Determination Method of Laser Derusting Control Parameters for Power Grid Equipment Based on Contour Geometric Feature Fusion
Based on the profile characteristics of laser derusting,determining the control parameters of power grid equipment derusting mainly relies on a single profile geometric feature,which results in a large deviation of derusted surface roughness after the parameters determination.An adaptive parameter determination method based on contour geometric feature fusion is designed.According to the working principle of laser derusting,the finite element model of laser derusting is established.The boundary moment analysis algorithm is used to extract the geometric features of the grid equipment derusting.Based on the fusion of multiple contour geometric features,a parameter determination method is designed to effectively select various control parameters.Through response surface analysis,the laser derusting control parameters of power grid equipment are adaptively determined.The experimental results show that the deviation between the derusted surface roughness and the target surface roughness can be reduced 2.7 μm.Compared with the setting results of other laser derusting control parameters,the derusted surface roughness deviation is reduced by 54.24％and 63.51％
