虚拟仿真实验系统的建模方法研究

Research on modeling methods in the virtual simulation experiments

摘要:

提出了虚拟仿真实验系统建模的“数学模型+图像模型”的模型结构,该模型从真实实验抽象出实验场景、仪器对象以及元器件对象,采用面向对象方法对它们进行数学建模与图像建模,完成对真实实验的虚拟；总结了虚拟仿真实验开发过程中的各种仿真建模方法和技术,包括数学模型的建立、静态和动态三维图像模型的建立、数学模型与图像模型的协调工作等；最后给出了面向对象的可重用建模方法,该方法具有良好的直观性、可扩展性和可重用性。

Abstract:

The mathematical model and image model based framework of model for virtual simulation experiment is proposed. In the model, the virtual experiment simulates physical experiments via abstracting scenes, instrument objects and element objects from them, and constructing mathematical and graphic models for them with object-oriented method. This paper summarizes kinds of modeling methods and technologies, such as the establishment of mathematical models, static and dynamic 3-D image models, cooperation of the models, etc. At last an object-oriented reusing modeling method that is comprehensible, expansible and reusable is also given.
