Abstract

See full text

Disclosed is a method, system, and electronic device for precision roll bending of cylinder with variable curvature section. The method first obtains process parameters of roll bending of a target cylinder, and then conducts roll bending rebound simulation of the cylinder based on the process parameters to determine influence factors of rebound compensation error. Then, multiple sets of different preset influence factor values are set to perform roll bending rebound simulation of different arc segments. This disclosure uses multiple simulations of the rebound caused by cylinder roll bending to determine the factors that affect the rebound compensation error and the magnitude of the rebound compensation error that may be caused by these factors. Finally, an expression for the rebound compensation error is obtained to correct the rebound compensation equation, eliminating the error caused by rebound compensation, and ensuring that the cylinder forming meets the expected accuracy requirements.
