SPVT系统的框架结构研究

目前,由物理模型、数值方法和可视化技术相结合而发展起来的仿真技术,受到广泛的重视,正在迅速发展.在振动工程界,利用计算机技术将振动试验与计算机仿真技术集成在一起也是一个追求的目标.虚拟振动仿真系统SPVT（Simulation Platform of Vibration Test）,是在对振动环境试验和振动环境试验的数值仿真分析的研究基础上,研制的具备试验项目管理、数据信息处理、试验控制、振动分析、夹具设计、模型修正、试验再现等多种功能的集成化系统.该系统基于分布式异构网络,以项目管理为核心,实现仿真自动化,为振动环境试验的发展探索出一种试验与计算机仿真相结合、相互促进的新途径.该文介绍了系统的框架结构和实现该结构的关键技术.

Design and Realization of the Simulation Platform of Vibration Test

At present,the simulation technology,which consists of physical model,numerical method,and visualization technology is developing rapidly and attached more importance.In the field of Vibration Engineering,integrating vibration test with computer simulation is a goal.SPVT is an integrating system which supports many functions such as information process,test control,vibration analysis and so on.The system is based on a distributed and heterogeneous network,focuses on project management and realizes automated simulation.All these attempts in technology are made for a new method of combining vibration test and computer simulation.In this paper,system architecture is put forward,and key techniques of realizing the architecture are also presented here.
