发动机进气道稳流试验台的开发 - The method of numerical simulation may used to improve the design of intake port , reduce the design time and design expense . at the same time , this article has the important science meaning and engineering application value
数值模拟方法可用来改进实际发动机进气道的设计，从而节省设计时间和减少设计费用，具有重要的学术意义和工程应用价值。 - Sum up , the study of intake port is significant for the design of intake port and the development of engine . at present , the study of flow characters in intake port of engine mainly depends on experiment . numerical simulation is not universal , especially for the engine with dual - intake port
目前，国内对发动机进气道的流动特性研究手段主要依靠实验，在实验台上进行大量的实验，既费时又费力，实验方法显得过于陈旧过时，已不能适应现代高性能发动机研制工作的需要，因此，采用多维数值模拟技术是一种有效的研究手段。 - Intake port is the important part of engine , the flow characters and the design of intake port of have the vital effects on the performance of engine . the structure of intake port affects the quantity of fresh air in cylinder and the strength of swirl , so affects the degree of combustion 、 components of exhaust and feasible energy of exhaust , and so on
进气系统是发动机的重要组成部分，系统内气流的品质和气道设计是否合理，对发动机性能及工作可靠性等都有很大的影响，发动机进气道的结构直接影响缸内新鲜空气充量的大小和吸入空气涡流的强度和程度，从而直接关系到发动机的燃烧完善度、排气的成分以及废气可用能量等。 - The results attained are as follows . on account of the strongly coupling character of parameters which have an effect on scramjet performance , the approximate evaluation models of scramjet inlet diffusion performance and the ignition problem in direct - connected experiments are established by neural network methodology
针对发动机性能影响因素强烈耦合的特点,采用bpnn和rbnn神经网络方法,分别建立了超燃冲压发动机进气道扩压性能和直连式发动机点火性能的神经网络近似评估模型,得到了很好的逼近效果和预测能力。
