Although stochastic resonance (SR) has been widely used to enhance weak fault signatures
in machinery and has obtained remarkable achievements in engineering application, the …

The benefits of noise can be found in nonlinear systems where a type of resonances can
inject the noise into systems to enhance weak signals of interest, including stochastic …

Stochastic resonance (SR) has been widely applied in the field of weak signal detection by
virtue of its characteristic of utilizing noise to amplify useful signal instead of eliminating …

Conventional bistable and monostable stochastic resonance (SR) methods exhibit certain
limitations in their capacity to enhance and extract incipient characteristics. Firstly, the …

When the load and speed of rotating machinery change, the vibration signal of rolling
bearing presents an obvious nonstationary characteristic. Stochastic resonance (SR) mainly …

In actual fault diagnosis, useful information is often submerged in heavy noise, and the
feature information is difficult to extract. A novel weak signal detection method aimed at the …

Condition monitoring of rotating machinery is important to extend the mechanical system's
reliability and operational life. However, in many cases, useful information is often …

The early fault signal of rolling bearings is very weak, and when analyzed under strong
background noise, the traditional signal processing method is not ideal. To extract fault …

Rotating machinery devices are prone to failure due to severe working conditions, whose
failures will further induce other mechanical faults. Therefore, the fault diagnosis of rotating …
