Title:
DEFORMATION PREDICTING SYSTEM AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/021820
Kind Code:
A1
Abstract:
The deformation predicting system that calculates, by FEM analysis, weld deformation of a structure (130) manufactured by performing spot welding, includes: a structure data fetching process (S1); a welding point extraction process (S2); an FEM analysis model creation process (S3); a nugget element setting process (S4) that involves creating a nugget element (340) as an FEM analysis model for a spot welding point (140) at the position of the spot welding point (140) and sets, in the nugget element (340), an inherent deformation caused by resistance heating at the spot welding point (140) and by pressure on the spot welding point (140) when performing the spot welding; and a weld deformation calculation process (S5).
