Abstract: |
This paper studies the processing method of engine performance test data.Using the least square piecewise polynomial fitting method to fit curve,the working efficiency and test accuracy could get great improvement.Using the coordinate transformation method could further enhance the fitting accuracy.Using the linear interpolation method of binary schedule function,the computer processing of air correction could be realized. |
Key words: engine performance test curve fitting data processing |
