3Dプリンティング技術に基づく自動車のシャシー用部品のトポロジー最適化構造の作製および加振試験による実験的評価

抄録

In this paper, we present the result of vibration test using the automobile chassis parts fabricated by 3D printer based on the topology optimization results. In the topology optimization analysis, the strain energy minimization analysis was carried out, and the optimized shapes were obtained by changing the initial density conditions. The shapes were fabricated by 3D printer, and the practical vibration tests were performed. Consequently, it was found that same tendency can be obtained between numerical and experimental results.
