多学科设计优化已成为一种强有力的技术，以促进复杂和多学科产品的持续改进。参数化建模是多学科设计优化的重要组成部分，对多学科设计优化的灵活性和鲁棒性有着重要影响。本文研究了关系和非关系参数化技术对多学科产品概念设计鲁棒性和灵活性的影响。通过对关系参数化与非关系参数化的对比分析，以及它们对柔性和鲁棒性的影响，表明关系参数化是多学科设计优化过程中的一种有效方法。该方法的固有属性有助于提高不同学科之间的沟通，一个有效的参数化建模。这增强了多学科设计优化过程的性能，并允许更灵活和鲁棒的设计。所考虑的学科是计算机辅助设计，计算流体动力学，有限元分析和动态模拟。在计算机辅助设计环境中创建的高保真几何形状是以计算机辅助设计为中心的方法，后来用于计算流体动力学，有限元分析，以便更好地了解产品，因为它会导致精确的结果。所提出的方法实施的概念设计的一种新的产品，潮汐发电厂开发的Minesto AB使用多学科设计优化过程。
Multidisciplinary design optimization has become a powerful technique to facilitate continuous improvement of complex and multidisciplinary products. Parametric modeling is an essential part with tremendous impact on the flexibility and robustness of multidisciplinary design optimization. This article investigates the effect of relational and non-relational parameterization techniques on the robustness and flexibility of the conceptual design of a multidisciplinary product. Bench marking between relational and non-relational parameterization and their effect on flexibility and robustness indicate that the relational parameterization is an efficient method in the multidisciplinary design optimization process. The inherent properties of the method contribute to an efficient parametric modeling with improved communication between different disciplines. This enhances the performance of the multidisciplinary design optimization process and allows a more flexible and robust design. The considered disciplines are computer-aided design, computational fluid dynamics, finite element analysis, and dynamic simulation. A high-fidelity geometry created in a computer-aided design environment is computer-aided design centric approach and later used in computational fluid dynamics, finite element analysis for a better understanding of the product as it leads to precise outcomes. The proposed approach is implemented for the conceptual design of a novel product, a tidal power plant developed by Minesto AB using a multidisciplinary design optimization process.
