Abstract

This paper describes an innovative method which automatically calculates the material properties and boundary conditions which must be applied to an axisymmetric Finite Element (FE) model of a quasi-axisymmetric component, to account for the fact that some regions in a quasi-axisymmetric model are not fully axisymmetric. The automated process has been implemented using the Application Programming Interface (API) of a commercial FE package and builds on an existing process which automatically creates an axisymmetric FE mesh from a 3D CAD model of a quasi-axisymmetric component. The method is demonstrated for a series of component models. For the thermal analysis of an aerospace turbine rear structure model, the FE model was created from the 3D CAD model in approximately 2 min and gave nodal temperatures within 9% of a 3D FE model.

自动逼近准轴对称部件轴对称热分析所应用的材料特性和边界条件

本文介绍了一种创新方法，该方法可自动计算准轴对称部件的轴对称有限元 (FE) 模型必须应用的材料属性和边界条件，以考虑准轴对称模型中某些区域并非完全轴对称的事实。该自动流程是利用商业 FE 软件包的应用编程接口 (API) 实现的，并建立在现有流程的基础上，该流程可根据准轴对称部件的 3D CAD 模型自动创建轴对称 FE 网格。该方法针对一系列组件模型进行了演示。在对航空涡轮后部结构模型进行热分析时，从三维 CAD 模型创建 FE 模型仅需约 2 分钟，节点温度控制在三维 FE 模型的 9% 以内。

期刊介绍： The aim of this journal is to provide ideas and information involving the use of the finite element method and its variants, both in scientific inquiry and in professional practice. The scope is intentionally broad, encompassing use of the finite element method in engineering as well as the pure and applied sciences. The emphasis of the journal will be the development and use of numerical procedures to solve practical problems, although contributions relating to the mathematical and theoretical foundations and computer implementation of numerical methods are likewise welcomed. Review articles presenting unbiased and comprehensive reviews of state-of-the-art topics will also be accommodated.
