The present invention belongs to the field of energy-absorbing metamaterial design, and specifically relates to a method for designing energy-absorbing metamaterials based on a diffusion model and parameter optimization. The present invention proposes a method for designing energy-absorbing metamaterials based on a diffusion model and parameter optimization, which generates metamaterials given a required stress-strain curve.

In order to improve the accuracy and generalization performance of the diffusion model, a new method is proposed to parameterize the generated metamaterial, and at the same time use a genetic algorithm to fine-tune it, so that the optimized mechanical properties of the metamaterial are consistent with the target stress-strain curve. In summary, the present invention has the advantages of fast design speed and high accuracy, and provides a new solution path for realizing more intelligent and customized energy-absorbing metamaterial design.
