摘　　要：ABAQUS是目前最先进的大型通用非线性有限元分析系统,也是唯一应用了特征技术的有限元分析软件。通过剖析其特征技术应用的特点及其问题,对自主开发基于特征的有限元建模软件具有重要的参考价值。首先介绍了ABAQUS中基于零件和装配概念的有限元模型的建模方式,其次分析研究了ABAQUS前处理模块ABAQUS/CAE中的特征技术及其应用特点,具体分析并总结了其形状特征的分类及生成方法,剖析了ABAQUS中分析属性(分析类型、材料、载荷和边界条件等)与特征之间的关系,网格生成与特征之间的关系,最后指出了其特征技术应用存在的不足和缺陷,并给出了进一步改进的一些建议。Nowadays, ABAQUS is the most advanced finite element analysis system for solving non-linear problems in the world. It is also only one finite element analysis system which applies feature technology. Studying its characteristics and some problems of feature technology application is very important for developing feature-based finite element modeling software by ourselves. Firstly, this paper introduces the modeling mode of ABAQUS which is based on the conceptions of part and assemble, secondly, studies feature technology and its applications in ABAQUS/CAE the preprocessing module of ABAQUS, concretely analyzes and summarizes the category of form feature and its generation methods, especially studies relationship between form feature and analysis attribute feature （analysis type, material, load and boundary conditions etc.）, relationship between form feature and mesh generation, finally, the paper points out that ABAQUS has some deficiencies in applying feature technology, and provides some advice for improving the functions of ABAQUS.
