Title:
METHOD FOR CALCULATING HEATING PLAN USED FOR BENDING METAL PLATE BY LINE HEATING
Document Type and Number:
WIPO Patent Application WO/2021/182334
Kind Code:
A1
Abstract:
The present invention is a method for calculating a heating plan used for bending a metal plate by line heating. This calculation method is provided with: a step for repeating, while changing the position of a heating line, a first trial in which a structural analysis is carried out using a first heating condition with a heating line, which has been set in an analysis model, and the analysis result and a first target shape are compared; a step for selecting, as a first selected heating line, a heating line set in the first trial for which the analysis result was close to the first target shape, among the repeated first trials; a step for repeating, while changing the position of the heating line, a second trial in which a structural analysis is carried out using a second heating condition with a heating line, which has been set in the analysis model, and the first selected heating line, and the analysis result and a second target shape are compared; and a step for selecting, as a second selected heating line, a heating line set in the second trial for which the analysis result was close to the second target shape, among the repeated second trials.
