Title:
CALCULATION METHOD FOR HEATING PLAN, PROGRAM, RECORDING MEDIUM, DEVICE, DEFORMATION METHOD, PLATE DEFORMATION DEVICE, AND PRODUCTION METHOD FOR DEFORMED PLATE
Document Type and Number:
WIPO Patent Application WO/2022/191301
Kind Code:
A1
Abstract:
The present invention provides a calculation method that makes it possible to quickly calculate a heating plan for bringing a plate closer to a target shape. This calculation method is a method for calculating a heating plan for heating and thereby deforming a plate. The calculation method comprises a Bayesian optimization step and a finite element analysis step. The Bayesian optimization step is for performing a Bayesian optimization on a training data group and determining a heating conditions candidate. The training data group includes a plurality of combinations of: heating conditions that include a heating shape that has been set at an arbitrary location on an analysis model for the original shape of the plate; and a shape that has been calculated on the basis of the heating conditions. The finite element analysis step is for converting the heating conditions candidate into strain data and performing a finite element structural analysis on the strain data to output a shape candidate.
