摘要
设计开发新的涡扇发动机是一项复杂耗时的工程,而计算机仿真是一种有效的解决办法。因此开发比较通用的计算机仿真模型已经成为一种发展趋势。本文以面向对象技术为基础提出了建立通用化的发动机模块化模型库的思路,并依据该指导思想在新的面向对象的仿真工具—Modelica语言基础上最终开发出一个包含涡扇发动机各部件在内的模型库,详述了模型库构建流程及其结构。在此基础上进一步建立了一个带开关磁阻电机的混合排气涡扇发动机模型。最后通过对其进行仿真来验证该模型库的实际效能并获得满意结果。
The design and development of new turbofan engine is time consuming and expensive, while computer simulation is a promising method to solve the problem. Based on the object oriented technology and new simulation tool---- Dymola/ Modelica, the paper gives a design pattern for developing a generic modular-modeled library of air gas turbine and then builds it. The hierarchical structure, extensible and standardization are the characteristics of this library. It enables users to customize and extend the framework to add new functionality or to adapt the simulation behavior as required, and it allows new models to be composed programmatically or graphically to form more complex models. The model library can be used in steady state and transient state analysis of the aero engine. It is also a user-friendly, accurate, fast PC-based and easily reusable simulating tool. A double tools turbofan engine with switch reluctance generator model is constructed based on this library. The model and the library have been validated through simulation.
