DEFORMATION STATE ANALYSIS METHOD, RESIN MOLDED ARTICLE DEFORMATION IMPROVEMENT METHOD, AND RESIN MOLDED ARTICLE WEIGHT REDUCTION METHOD

摘要

Provided is an analysis method which, when a plan for measures against the deformation of a resin molded article (for example, a plan for measures against warp deformation) is created and designed, enables a reduction in time and a significant cut in calculation cost to thereby create a more effective plan for measures.A deformation state analysis method wherein, regarding a deformed resin molded article, the deformation state of the resin molded article is analyzed by separating the resin molded article into minute regions and optimizing a target function under a predetermined constraint condition and a predetermined restriction condition using a phase optimization method, the predetermined constraint condition is the tendency of the deformation amount of the resin molded article, the predetermined restriction condition is a contribution rate indicating the degree of contribution of the deformation of each of the minute regions to the deformation of the resin molded article, and in the optimization of the target function, the optimization is performed such that the reduction of rigidity of the resin molded article is minimized.
