RISInfluence of Poisson White Noise on the Response Statistics of Nonlinear System and Its Applications to Bearing Fault Diagnosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In view of complex noise background in engineering practices, this paper presents a rescaled method to detect failure features of bearing structure in the Poisson white noise background. To realize the scale transformation ...
On the Weak Signal Amplification by Twice Sampling Vibrational Resonance Method in Fractional Duffing Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In our former work developed by Yang et al. (2017, “Enhancing the Weak Signal With Arbitrary High-Frequency by Vibrational Resonance in Fractional-Order Duffing Oscillators,” ASME J. Comput. Nonlinear Dyn., 12(5), p. ...
Adaptive Stochastic Resonance for Bolt Looseness Identification Under Strong Noise Background
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nowadays, a large number of mechanical equipment working in harsh working environment will lead to strong background noise, which makes it difficult to extract feature information related to equipment fault. Bolt joint ...
