In this article, a novel E-exponential SR model and weak signal detection method are proposed for the detection of weak defect signals in steel wire rope. The model is introduced from the perspective of Taylor expansion and nonlinear system analysis, and its performance is evaluated through simulation and analysis. Experimental comparisons and case studies are conducted to demonstrate the validity of the proposed method.
Steel wire rope can be frequently damaged by various factors. Although weak defect signal detection is the key to guarantee safety, current classic stochastic resonance (SR) models and methods are unavailable due to the complicated interference of noise. Thus, in this article, a novel E-exponential SR model and weak signal detection method are proposed. The principle of this model is first introduced from the perspective of Taylor expansion and nonlinear system analysis. Then, the model performance is simulated and evaluated by output signal analysis and chaos characterizations. Afterward, model comparison with different system parameters, experiments, and case studies regarding three typical wire rope defects inspection and weak signal recognition is conducted to demonstrate the validity of the novel method. Finally, the advantages and limitations of the proposed SR model are discussed.
