| 摘 要： | 虚拟装配环境中一个关键问题是装配环境在代码层、数据存储层、几何模型层、物理模型层、显示层及装配对象层的数据一致性。该文通过对装配体的分析，讨论了分层树状数据模型的实现方法。方法使用基于面向对象的概念和树结构清晰而简洁地将装配体在多个层次上有机的连接起来，实现了装配环境中各种数据的统一，提高了虚拟装配环境中数据的存储、表达的有效性。

| Abstract: | A key question in virtual assembly environment is the consistency of data in assembly environment on code layer, data storage layer, geometric model layer, physics model layer, display layer and assembly object layer. In this paper, an approach for realizing multilevel tree-model through the analysis of assembly object is introduced. The approach is to connect assembly objects in some layers based on the theory in Object Oriented and tree frame, to realize the unification of all kinds of data in assembly environment. In this way, validity of storage and delivering of data can be enhanced in assembly environment. |
