摘要
根据PUMA试验台架上得到的某型发动机稳态、动态有关参数的数据,基于仿真分析软件MATLAB,运用小波分析等手段对试验数据进行了处理,分析得到了该型发动机的有关特性。在完成数据处理的基础上,建立了主要基于试验数据查表描述法的发动机仿真模型。仿真结果验证了所建模型的有效性,证明了所提出的发动机试验数据处理方法的正确性和有效性。
The steady and dymamic testing data of an engine acquired on the PUMA engine test bed were processed by using wavelet analysis based on MATLAB, and the characteristics of this engine were obtained. On the basis of data processing, an engine simulation model based on the look-up table method was developed. The simulation results verify the validity and accuracy of the data processing method and the model.
