description The invention relates to a substructure-based large wall plate continuous riveting deformation prediction method. The method includes using Finite element software ABAQUS as a tool to carry out simulation calculation; building an airplane multi-nail wall plate equivalent simulation model; dividing a riveting area in the model into a plurality of single-nail local riveting entities; when hundreds or thousands of rivets are arranged on the wall plate, converting prediction of wallboard riveting deformation from sequential simulation of the riveting process of each rivet into no consideration ofthe riveting process of the rivet, and only taking the bending moment generated by the rivet of the specification in the single-rivet riveting process as the loading condition and sequentially loadingto the corresponding node of each assembly coupling surface on the wallboard. According to the method, the calculation efficiency is greatly improved, the result of wallboard riveting deformation israpidly obtained, and a bas
