Research on Fault Diagnosis of Intermediate Bearing Based on Adaptive Bistable Stochastic Resonance

在发动机构成体系中,发动机的运行状态与作业性能会在很大程度上受到支撑传动系统的影响,而中介轴承更是其中非常重要的影响因子之一。一旦出现故障,势必会直接影响支撑传动系统的运行性能。据此提出一种基于自适应双稳态随机共振系统的中介轴承故障诊断措施,通过自适应双稳态随机共振系统对中介轴承故障特征进行提取,以支持后续故障监测、诊断工作的顺利实现。

In the engine system,the running state and performance of the engine will be greatly affected by the supporting transmission system,and the intermediate bearing is one of the most important factors.Once there is a fault,it will directly affect the operation performance of the supporting transmission system.Therefore,a fault diagnosis method based on adaptive bistable stochastic resonance system is proposed in this paper.The fault features of the intermediate bearing are extracted by the adaptive bistable stochastic resonance system to support the subsequent fault monitoring and diagnosis.
