摘要: 本文提出燃气轮机系统仿真集成的概念, 分析了关键实现技术, 然后从跨平台性入手, 给出 1个分布异构计算机平台上的面向对象实现方案。算例表明, 这一方案成功实现了系统仿真集成的主要功能, 从而为发动机系统的多学科开发、研制和实验提供了有效的仿真软、硬件平台, 并使发动机的远程协同设计成为可能。Abstract: In order to systematically, rather than analytically investigate the interdisciplinary phenomenon during the engine's life cycle,the concept of gas turbine simulation integration is proposed.The technological obstacles in its realizeation are identified.Then a prototype distributed object implementation is presented from the viewpoint of the cross platform attribute of the simulation integration.For engine overall performance simulation based on its components' performance on a heterogeneous distributed computing platform,the IEEE standard for distributed object computing,CORBA,is conformed throughout the implementation.The implementation is tested on a network environment consisting of 3 Pentium Ⅱ PCs and 1 SUN Ultra 1 workstation interconnected through a LAN.The functionality of simulation integration is fully verified and various simulation results of different configurations are presented and analyzed.It is concluded that,without real time support,the above implementation can only be used in interdisciplinary researches not requiring any real time capabilities.Some potential applications of the implementation,including remote collaborative engine design and simulation,are also proposed.
