一种基于ACE/TAO的航空发动机分布式仿真方法

Distributed Simulation Method Based on ACE/TAO for Aero-engine

提出一种新的航空发动机分布式仿真方法。基于面向对象技术建立某型航空发动机部件级模型并运用符合OMGCORBA(ObjectManagementGroup,CommonObjectRequestBrokerArchitecture)规范的ORB(ObjectRequestBroker)——ACE(AdaptiveComputingEnvironment)/TAO实现模型之间的通信。基于部件级串行方式的整机仿真数据表明该方法的准确性和可靠性。在此基础上设计基于求解非线性方程组的并发分布式仿真算法,对仿真试验数据进行分析得出影响分布式仿真性能的重要因素。研究的航空发动机分布式仿真方法与面向对象技术融为一体,提供了灵活易扩展和维护的航空发动机分布式仿真框架,为高精度航空发动机复杂模型部件集成、多精度分析、多学科耦合仿真奠定基础。

A new distributed simulation method for aero-engine was proposed, which used a ORB （Object Request Broker） conforming to the OMG CORBA （Object Management Group, Common Object Request Broker Architecture） standard--ACE/TAO to achieve the correspondence of component models based on OO （Object Oriented） technology. Simulating under different network environments in serial mode of component-level, the result indicates its accuracy and reliability. A concurrent algorithm for distributed simulation was designed based on solving the nonlinear equations. The key factors determining the performance of distributed simulation were obtained by analyzing test data. The method studied combines well with O0 technology, providing an easy-extending and maintaining distributed simulation framework for aero-engine, which lays a foundation for aero-engine models of high complexity and the parallel simulation.
