Aiming at the characteristics of Aeronautical thin-walled part(ATWP)such as thin wall and low rigidity,to optimize the fixture locating layout and improve the fixture design efficiency,aprediction model for ATWP fixture locating layout design and optimization was developed.The training and testing data sets were generated by running only a few times of Finite Element Analysis(FEA)on the design sites standing for different fixture locating layouts selected through Latin Hypercube Design(LHD).The locating lay...
