| Abstract: | On the basis of the characteristics of the Duffing equation's solutions, the chaotic oscillators are designed. This kind of oscillators can present the properties of sensitive dependence on weak signal and immunity to noise, so they can be used to detect the weak signals. This method can also be used in early detecting rub-impact fault of rotor system. The result shows that this method is simple and feasible. |
