摘要
为提高耐压柱壳设计效率,设计了耐压柱壳参数化分析流程。研究了有限元分析所涉及的材料属性、载荷施加、边界条件设置等内容,确定了采用弧长法分析耐压柱壳稳定性。利用Python语言对于ABAQUS软件进行了二次开发,利用Isight软件实现了ABAQUS的集成,实现了耐压柱壳有限元分析模型的网格自动划分、自动分析计算等。选择样本点进行参数化分析,利用响应面模型对于样本点进行了拟合,得到了具有较高拟合精度、满足工程需要的近似模型,进行了设计变量的灵敏度分析。研究结果表明:参数化分析流程可实现耐压柱壳的自动分析、近似模型及灵敏度分析,可降低耐压柱壳分析难度,均可提高耐压柱壳设计效率。
In order to improve the design efficiency of pressure-resistant cylindrical shells, the parametric analysis process is designed for pressure-resistant cylindrical shells. Material properties, load exertion and boundary conditions involved in finite element analysis are studied, and the arc length method is adopted to analyze the stability of pressure-resisting cylindrical shells. The ABAQUS software is redeveloped by Python language, and the integration of ABAQUS is realized by using the Isight software. Automatic mesh generation,automatic analysis and calculation of the finite element analysis model of pressure cylindrical shells are also realized in this paper. The sample points are selected for parametric analysis, the response surface model is used to fit the sample points. The approximate model is obtained, with high fitting accuracy and satisfying engineering needs, before. the sensitivity analysis of design variables is carried out. Research results show that parametric analysis process can realize the automatic analysis, approximate model and sensitivity analysis of pressure-resistant cylindrical shells, and reduce the difficulty of analysis, thus improving the design efficiency of pressureresistant cylindrical shells.
