| Abstract: | In diagnosis of engine, working conditon is the basis of data analysis, condihon evaluahon and fault diagnosis. Rotating speed signal shows the working condihon.Speed varies with different working condihon. The speed - time model can be obtained by polynomial regression under different working condihon. On the basis of fuzzy pattern recognizaton method, prachcal working condihon can be determined. |
