摘要: 基于java的面向对象建模, 建立了可扩展的推进系统仿真平台(EPSP).研究了EPSP中分级模型建立的机制;基于组件分解和标准化接口, 提出了EPSP中所用的工程模型架构的设计.EPSP允许部件被其它类似功能的部件替换, 用户可以自己组建推进系统模型, 并进行各学科和各精度的仿真计算.如何构建EPSP的工程模型将被描述, 文中给出了部件工程模型创建的示例, 表明可以利用本平台很方便的架构推进系统模型, 体现了“插件化”的思想, 证明本平台的建模达到了预期的目标.Abstract: EPSP(extensible propulsion simulation platform) was developed as a Java-based object-oriented platform for propulsion system simulation.The architecture represents the hierarchal structure of the engine,its components and substructures using recursive composition.This paper presents the design of a common engineering model framework for use in EPSP.This technique provides an access to build models with increasingly complex elements out of simpler ones.The foundations of the platform's engineering model were described.To test the platform,we can easily construct a component based engineering model,and the "pluggability" of the architecture is shown.The example proves the validity and feasibility of the modeling of the platform.
