项目摘要

The projects research hypothesis is that, with an adjusted method, it is possible to develop lightweight structures out of fiber composite material to not only reach low mass properties but also to be efficiently manufacturable. As a consequence, high engineering and production costs compared to metal designs can be reduced. The objective is to develop and evaluate a method for the automated design of high-performance fiber composite structures and their efficient production. This comprises structural design, production planning and their interaction. The quality of a solution is determined by structural criteria (mass) as well as production criteria (production cost). Compared to conventional methods, an early consideration of production aspects prevents cost-intensive iterations in later stages of the development process. Conventional methods can only select a limited amount of solutions in the concept phase since all of them are to be fully developed in the following development steps. This method, however, is able to consider a higher number of solutions that differ in structural and production aspects. The overall development effort can be limited by gradually proceeding through the design of all solutions in parallel. In the course of this process the complexity of applied design and assessment methods is increased while the number of considered solutions is decreased. Therefore, complex methods are only used for a smaller number of solutions that qualified in preceding selections. As an application example the development of an aircraft fuselage structure made of carbon fiber reinforced plastic (CFRP) is chosen, since it has extreme requirements that can only be met in an optimum way by using an approach with strong interaction of both disciplines. The research is based on achievements of an interdisciplinary cooperation of the institutes in the field of high performance production of CFRP-structures practiced since 2010.

该项目的研究假设是，通过调整方法，可以开发出纤维复合材料的轻质结构，不仅可以达到低质量性能，而且可以有效地制造。因此，与金属设计相比，可以降低高的工程和生产成本。目的是开发和评估一种高性能纤维复合材料结构的自动化设计及其高效生产的方法。这包括结构设计、生产规划及其相互作用。解决方案的质量取决于结构标准（质量）和生产标准（生产成本）。与传统方法相比，早期考虑生产方面可以防止开发过程后期阶段的成本密集型迭代。传统方法只能在概念阶段选择有限数量的解决方案，因为所有这些解决方案都将在以下开发步骤中得到充分开发。然而，这种方法能够考虑更多在结构和生产方面不同的解决方案。通过并行地逐步设计所有解决方案，可以限制总体开发工作。在此过程中，应用设计和评估方法的复杂性增加，而考虑的解决方案数量减少。因此，复杂方法仅用于在前面的选择中合格的较少数量的解决方案。作为一个应用实例，选择了碳纤维增强塑料（CFRP）制成的飞机机身结构的开发，因为它具有极端的要求，只有通过使用两个学科的强相互作用的方法才能以最佳方式满足。该研究基于自2010年以来在CFRP结构高性能生产领域的研究所跨学科合作的成果。
