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.EPSP提供了一个灵活的仿真环境, 可以定义、修改和仿真基于组件的推进系统模型.EPSP具有友好的图形化界面, 可以方便地修改推进系统各部件的参数, 用户可以进行定制和扩展, 以增加新功能或者适应所需的仿真行为.本文分别介绍了EPSP的可视化框架和连接服务框架, 并且研究了计算框架的设计思想.文中给出了某双轴涡扇发动机动态仿真的算例, 结果表明, EPSP是进行扩展灵活的推进系统仿真计算的有力工具.Abstract: EPSP(Extensible Propulsion Simulation Platform)was developed as a Java-based object-oriented platform for propulsion system simulation.EPSP provides a flexible environment for defining,modifying and simulating the component-based propulsion models.EPSP has a friendly GUI for easily modifying parameters of the components.EPSP enables users to customize and extend the framework to add new functions or adapt simulation behavior as required.The visual assembly framework and the connection services framework were introduced,and the design pattern of the computation framework was studied.An example of transient simulation of a twin-spool turbofan engine was provided.It shows that EPSP is effective in extendable and flexible simulation computation for propulsion system.
