Continuous simulation method for stress and deformation in manufacturing process of welded aircraft panel

The invention discloses a continuous simulation method for stress and deformation in the manufacturing process of a welded aircraft panel, and belongs to the technical field of process chain continuous simulation. According to the method, a whole set of finite element modeling method for carrying out continuous simulation of a wallboard manufacturing process chain is provided aiming at three working procedures of hot die bending, assembling and welding and postweld heat treatment of a welded aircraft wallboard, so that residual stress and deformation of a skin after hot die bending can be reproduced; and continuous assembly, welding and heat treatment simulation of stringers can be realized on the skin with dimensional deviation and initial stress, continuous evolution of stress and deformation of the welded aircraft panel among different procedures is fully considered, and the problems of poor precision, low reliability and the like caused by carrying out aircraft panel welding simulation based on a zero-str
