摘　　要：针对某燃气轮机盘-片,运用存储与导入的思想提出了一套耦合场及接触问题的建模和分析的新方法。文中采用PRO/E建立了轮盘和叶片的三维实体模型,并结合ANSYS软件建立了其耦合场及接触有限元模型,详细介绍了该问题的有限元分析方法。文章最后给出了算例,其分析结果证明了文中的建模及分析方法是较好的适合工程应用的新方法。Aiming at the turbine disc - blade of a certain gas turbine, a series of new methods of modeling and analysis for coupling field and contact problem were obtained using the idea of save and import. In this paper, a three--dimenslonal model of turbine disc - blade was con- structed using the software PR0/E and the finite element models of coupling field and contact problem were also constructed using the software ANSYS. At last the finite element analysis for this question was introduced detailed. At the end of the text, an example of the analysis was giv- en, and the result proves that the method of modeling and analysis introduced in this paper is a good one for engineering application.
