“…Competitive failure has always been a hot topic in reliability research. Zhu et al [21,22] evaluated a system's reliability by studying the competitive process of sudden failure caused by random impact and degradation failure caused by the degradation process, considering the impact on degradation trajectory and degradation rate. Zhao et al [23] described the degradation process of a low-voltage switchgear through the Wiener process, simulated sudden failure through exponential distribution, and described different failure situations through the ratio of median life of degradation failure to accidental failure to evaluate the reliability of a low-voltage switchgear.…”

“…Zhang et al [7] used PFC 3D software 5.0 to simulate the cutting process of the pick, conducted cutting experiments on different coated picks, calculated the mass loss before and after cutting, and then predicted and analyzed the life of the pick. Qin et al [8] proposed a reliability model for the competitive failure of picks under random load impact by considering the effects of sustained impact, variable rate acceleration degradation, and hard failure threshold changes on pick wear. Tian et al [9] proposed a degradation model based on the Gamma process to describe the wear and tear of picks on the tunneling machine, realizing the prediction of the remaining life of picks.…”
