DESIGN ASSISTANCE DEVICE AND DESIGN ASSISTANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2023/233931
Kind Code:
A1
Abstract:
Provided is a design assistance device that generates a proposal drawing from the results of a structural optimization calculation for deriving a density distribution optimized for a structure, said design assistance device comprising: a clustering condition input unit that receives input of a clustering condition; a clustering unit that performs clustering in accordance with the clustering condition; a machine learning control unit that performs machine learning on each cluster obtained by means of the clustering; a drawing generation unit that generates a new drawing from the results of the machine learning; a drawing differentiation unit that compares a preliminary drawing to be compared and the new drawing and determines whether the drawings are identical; an optimization and analysis condition input unit that receives input of a calculation condition necessary for a structural optimization calculation; an analysis model generation unit that generates an analysis model in accordance with the calculation condition; a structural optimization calculation unit that uses the analysis model to perform the structural optimization calculation; and a drawing generation condition input unit that displays the results of the structural optimization calculation and the results of performing the clustering, and receives input of weights for each cluster necessary for drawing generation, wherein the drawing generation unit uses the results of the structural optimization calculation and the weights to generate the proposal drawing. In this way, it is possible to generate a high-quality drawing, in a short amount of time, from the density distribution of a structure derived by means of a structural optimization calculation.
