摘要：Considering the evolution of structure parameters of cone crusher, and based on the continuous-time and Ito Lemma, a model of evaluation and dynamic forecast on liner's reliability is studied in this paper. The performance of liner is fluctuant due to the uncertain factors (such as wear and adjustment of closed side setting) and gradually degraded. The degradation will influence the safe usage and reliability of liner. Degradation process of liner can be described by stochastic process and is modeled in geometric Brownian motions (GBM), and it is predicted with experimental data from a PYGB1821 cone crusher. The results show that the deviation between the predicted value and the experimental data is 2.62%. The model is valid on assessing the reliability of the liner, and the liner can be designed with the specified reliability value at the given time.
