VRML在水泥生产过程层次仿真模型库研究中的应用

从层次法的角度出发，运用模块化建模的方法，进行了水泥生产过程计算机仿真模型库的研究，遵循模块划分的原则，结合生产实际，把水泥生产系统划分为若干个子系统和对象，然后用VRML语言逐一完成这些子系统和对象的三维动画构造，从而构建原始的仿真模型库，应用层次法，通过构建更加复杂的模型，并将其添加到模型库中，实现了模型库的动态增长过程，最后，作者又讨论了层次模型库的结构，这是一种树型结构，从而使层次仿真模型库具有更大的可组性和灵活性。

Application of VRML in the Hierarchical Simulation Modellibrary of the Cement Producing Process Computer Simulation

In this paper, the modular modeling technique based on hierarchical method is utilized to research the cement producing process computer simulation. Complying with the modular dividing principle, we divide cement producing system into some certain subsystems and objects. Then, VRML language is employed to construct the three-dimensional animation of the objects and submodels which form the primary simulation model library. Building the more complex models with hierarchical method and adding them into model library, we realize the dynamic increasing process of the simulation model library. At last, we discuss the structure of the model library which has the tree type construction and accounts for the reorganization and the flexibility of the model library.
