摘要
鉴于特征技术在工程设计中的广泛应用，本文将特征技术引入有限元网格划分之中。结合塑性成形领域中的冲压产品特征设计，首先定性描述了特征对有限元网格划分的意义，提出了基于特征变化过程的有限元网格划分方法；然后讨论了如何实现特征对有限元网格划分的定量指导。
In consideration of the comprehensive use of feature techniques in engineering design, this paper introduces feature techniques into the finite element mesh generation. Using the feature based design of press products as examples, this paper firstly describes the influence of features on mesh generation from the qualitative viewpoint and then discusses how features quantify the mesh size.
