Abstract
En 中文
• A novel TFA technique is proposed for fault diagnosis of mechanical equipment. • The HOECT achieves TFR with high precision and concentration by constructing window parameter adaptive optimization criteria, along with the SEO and the CDA. • The effectiveness of the HOECT is validated through the multiple sets of simulated and real-world signals. • The HOECT can effectively characterize signals with close-spaced and crossed IFs.
