In this paper, a piecewise unsaturated tri-stable stochastic resonance (PUTSR) system is
proposed to address the issue of output saturation. Firstly, the unsaturated characteristics of …

In an effort to overcome the problem that the traditional stochastic resonance system cannot
adjust the structural parameters adaptively in bearing fault-signal detection, this article …

Quantifying fault severity is a critical part of rolling bearing health management. There are
numerous methods for evaluating the severity of rolling bearing faults that utilize various …

Weak signal detection methods based on stochastic resonance (SR) have been extensively
studied due to their capability to utilize noise energy for enhancing weak signals. Among …

In this paper, the dynamic system of ship rolling in random longitudinal waves induced by
Gaussian white noise (GWN) is studied analytically and numerically. The dynamic equation …

Incipient fault-induced weak impulses will not be detected easily using the existing fault
extraction methods. Stochastic resonance can flexibly use noises to enhance the signal-to …

The technique of energy harvesting, which captures the energy from ambient vibrations, has
received increasing attention due to its potential to power low-powered wireless sensors …

Abstract The Hindmarsh–Rose (HR) model is a three-dimensional oscillators susceptible to
initial values, making it capable of amplifying even the slightest variations. On this basis, we …

The establishment of stochastic delay Jeffcott rotor-seal system not only considers the track
irregularity caused by random noise and the possible influence of stochastic parameter …

The accurate extraction of weak signal features under strong noise background plays a
crucial role in the fault detection of rolling bearings. In order to promote the ability of …
