摘要:

在中国聚变工程实验堆(CFETR)集成设计平台(CIDP)的设计框架中,基于参数化模型开发了能够高效开展内冷屏设计优化的工作流程。通过OPTIMUS 软件驱动CATIA、ANSYS 等CAD/CAE 软件进行自动建模及有限元分析,利用响应面模型、敏感度分析等方法确定与优化目标关系密切的参数,该流程根据内冷屏的参数化模型的几何参数驱动优化流程得到满足设计判据的优化设计参数。在应用示例中,考虑到等离子体破裂工况下冷屏的安全运行要求,在电磁-结构分析得到的应力满足设计判据的前提下,通过优化几何参数使内冷屏的质量最小,从而降低建造成本、提高经济性。

Abstract:

In the integrated design framework provided in the CFETR integration design platform (CIDP), a workflow that can efficiently optimize the design of the vacuum vessel thermal shield (VVTS) was developed based on the parametric model. In the workflow, according to the geometry parameters of the parametric model of the VVTS, automatic modeling and finite element analysis in CAD/CAE software like CATIA and ANSYS can be driven by OPTIMUS software. The response surface model and sensitivity analysis are then used to determine the parameters which are closely related to the objective optimization. The optimized design parameters of the VVTS, which satisfy the design criterion, can be obtained by further optimization workflow. The application of the workflow is demonstrated by an example, where the safety requirement during plasma disruption events is considered. While the stress obtained by electromagnetic- structural analysis can meet the design criteria, the mass of the VVTS is minimized to reduce the construction cost and improve economics.
