摘要/Abstract

摘要： 提出了一种基于CAD零件离散体素模型的异质材料建模方法，重点对多材料模型和功能梯度材料模型建模进行阐述，提出固定参考特征活动梯度源(Fixed reference features & active gradient sources，FRF&AGS)的概念，引入复合AGS和不同方向FRF的建模算子，提高异质材料/零件建模的效率和灵活性。并将传统CAD实体建模的交、并、差等布尔算子扩展到异质材料零件的建模中。最后给出了设计实例。

Abstract: A framework on heterogeneous material part (HMP) modeling is proposed based on voxel model. The multiple material models and the functionally gradient models are mainly described. Fixed reference feature (FRF) and active gradient source (AGS) are introduced so that the efficiency and the flexibility of modeling process can be strengthened. An opera-tor for the models with multiple AGSs and different directional FRFs is defined. And the Boolean operators, such as intersec-tion, union and difference, are extended to HMP modeling. Then, two modeling examples are presented.

Key words: 3D CAD model, Active gradient source, Fixed reference feature, Heterogeneous material part, Voxel-based model
