摘　　要：提出了一种基于MATLAB语言的发动机性能试验数据处理与作图的新方法。在建立发动机特性数学模型的基础上,利用MATLAB语言的矩阵运算、三维曲线绘图等强大的数据处理功能,对发动机性能试验数据进行了曲线、曲面拟合,并绘制了发动机外特性曲线及万有特性图。结果表明,该方法具有数据处理精度高,物理意义明显直观,实用性强等优点。Based on Matlab,a new method to process the test data of engine performance and plot engine characteristics was introduced in this paper. On the basis of mathematic model of engine performance,by means of Matlab’s high data processing on matrix operation,3D graphics drawing,and so on,the test data of engine performance were fit with the curve and camber. Additionally,the external characteristic curve and universal characteristic curve were drawn.The results show that this method has several advantages such as high precision,intuitiveness,simplicity,strong practicality,and so on.
