FEA and GPR-based steel plate straightening stress state prediction method

The invention discloses a steel plate straightening stress state prediction method based on FEA and GPR, and relates to the technical field of steel plate straightening, and the method comprises the following steps: obtaining parameter information of a to-be-straightened steel plate, building a finite element simulation model of the to-be-straightened steel plate, and calculating; constructing a data set by using a result calculated by the finite element simulation model, and constructing a Gaussian process regression agent model; and inputting parameter information of the steel plate to be straightened into the proxy model, outputting a predicted stress value at the node of the steel plate to be straightened, and displaying a prediction result in a cloud picture rendering mode. On the basis of a finite element analysis method, after stress data in the straightening process are calculated, a regression agent model for stress prediction in the straightening process is constructed by using a Gaussian process re
