| Abstract: | Based on the basic equation of an certain type of aero-engine, a linear mathematic model is established in this paper. Two problems are solved mainly. Firstly, an improved piecewise smooth interpolation, which will replace the usual interpolation method, is presented to acquire needed parameters and partial differential values. Then, conversion formulae are given to acquire values of physical parameter partial differential from calculating parameter partial differential. Finally, computer simulation of dynamic characteristic under MATLAB environment is performed. |
