Abstract Stochastic resonance is the optimal response of nonlinear system to weak signals in noise background, which can enhance weak signals. Compared with traditional bistable systems, biased monostable systems exhibit good resonance characteristics under non-periodic pulse excitation. However, the parameters of the nonlinear system affect the optimal output of the system. For different aperiodic pulse excitation, the system is difficult to adjust adaptively. To solve these problems, this paper studies the biased monostable adaptive stochastic resonance under strong noise and aperiodic pulse excitation. First, adaptive stochastic resonance under different aperiodic pulse excitation is realized based on optimization algorithm. Then, taking the magnetic flux leakage detection signal of steel wire rope under strong noise background as the application object, after the output of adaptive stochastic resonance of the biased monostable system, the peak-to-peak value is used as the evaluation index of damage feature evolution to evaluate the difference between different weak damage features. At the same time, the bias monostable adaptive stochastic resonance method and the adaptive shift average method are used to compare and analyze the magnetic flux leakage signal of steel wire rope in the strong noise background. With the peak-to-peak gain and signal-to-noise ratio gain as indicators, the results show that the bias monostable adaptive stochastic resonance method is better than the adaptive shift average method. Finally, the influence of noise intensity on monostable adaptive Stochastic resonance is discussed, and it is found that biased monostable adaptive stochastic resonance has strong anti-noise ability.
