Description

Technical field [0001] The present invention relates to the field of mechanical modeling, particularly to a modeling method for the rebound curvature of a square pipe beam, apparatus, apparatus and storage medium. Background [0002] In the field of workpiece processing, the workpiece will be plastically bent, and the rebound curvature of the bend will be related to the final workpiece accuracy, so it is crucial to obtain the rebound curvature model before the workpiece is plasticized; [0003] In the prior art, the experimental method is usually used, that is, according to the bending test to measure the forming radius and forming angle, determine the bending radius and the forming radius, the relationship between the bending angle and the forming angle, according to which the mold and process design are carried out, but the experimental cost of this method is high, the efficiency is low, and the error is large, so it cannot provide an accurate reference for plastic processing. ...
