Abstract

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.
