This research project addresses an approach to fundamentally improve the state of the art procedure for the design of casting partsusing topology optimization under consideration of the production process. After passing through a topology optimization andsubsequent manual reconstruction, the geometry has to be simulated within every iteration of the product development process to ensure manufacturability. This sequential procedure has to be repeated until a satisfactory compromise between function and process is achieved. On this basis, a new approach for the combination of topology optimization and fast casting process evaluation based on a physical meta model will be explained. By integration of the meta model into the optimization environment, considerable time savings are achieved by reducing the number of manual reconstruction loops and thus process simulations needed.

本研究项目致力于从根本上改善铸件设计的最新水平--在考虑生产过程的情况下，使用拓扑优化。在经过拓扑优化和随后的手动重建后，必须在产品开发过程的每一次迭代中模拟几何图形，以确保可制造性。必须重复这一顺序过程，直到在功能和过程之间达到令人满意的折衷为止。在此基础上，提出了一种基于物理元模型的拓扑优化与快速铸造工艺评价相结合的新方法。通过将元模型集成到优化环境中，通过减少手动重建循环的数量从而减少所需的过程模拟，实现了相当大的时间节约。
