【Abstract】 Using the method of reconstructed phase space it is determined which type of elementary catastrophes is to be used in modeling of remnant life for a cracked rotor by means of calculating correlation dimension of the observed vibrational response data. On the basis of it, the paper gives a cusp model which is used to describe the development of crack of a rotor and its validity is also verified by experiments.更多还原
