VAEに基づく２次元音響問題におけるデザイン性を取り入れたトポロジー最適化

抄録

In general, structural optimization emphasizes the functionality of a structure through maximizing or minimizing a specific objective function. Therefore, it is interesting to realize the optimization that takes into account the design characteristics, as in humain design. To achieve this, we focused on the structural optimization method proposed by Guo et al. that incorporates dimensionality reduction by VAE, and applied it to an acoustic problem. In this article, we present an example of the sound pressure maximization problem at an observation point based on the experiments of Guo et al. We succeeded in obtaining optimized structures that takes into account the design constraints of the given design data and still performs the function.
