This paper presents a novel design methodology that validates and utilizes the results of topology optimization as the final product shape. The proposed methodology aims to streamline the design process by eliminating the need for remodeling and minimizing printing errors through process simulation. It also eliminates the repeated export and import of data between software tools. The study includes a case study involving the steering column housing of a racing car, where Siemens NX Topology Optimization was used for optimization, and verification analysis was conducted using the NX Nastran solver. The final solution was fabricated using AlSi10Mg via direct metal laser sintering on a 3D printer and successfully validated under real conditions. In conclusion, this paper introduces a comprehensive design methodology for the direct utilization of topology optimization, which was validated through a case study, yielding positive results.
本文提出了一种新颖的设计方法,该方法将拓扑优化的结果作为最终产品形状进行验证和利用。所提出的方法旨在通过消除重新建模的需求并通过工艺模拟将打印误差降至最低来简化设计过程。它还消除了软件工具之间数据的重复导出和导入。该研究包括一个案例研究,涉及一辆赛车的转向柱外壳,其中使用西门子NX拓扑优化进行优化,并使用NX Nastran求解器进行验证分析。最终解决方案是通过在3D打印机上使用AlSi10Mg进行直接金属激光烧结制造的,并在实际条件下成功验证。总之,本文介绍了一种直接利用拓扑优化的综合设计方法,该方法通过案例研究得到验证,取得了积极成果。
