Dynamic Analysis of Transmission Gears With Combined Tooth Wear and Root Crack Failures
Shock and Vibration, Volume 2025, Issue 1, 2025.Compound faults present a considerable challenge in fault diagnosis for gear transmission systems, as existing studies predominantly focus on individual failure modes. To address this limitation, the present study proposes a novel dynamic response analysis model that simultaneously considers tooth profile wear and root crack faults.

Effect of Structural Parameters on the Vibration of Slewing Bearing Under External Loading
Shock and Vibration, Volume 2025, Issue 1, 2025.As the main bearing component of the tunnel boring machine (TBM), the three‐row roller slewing bearing is required to withstand a heavy load and overturning moment in the tunnelling process. Therefore, a dynamic model of a slewing bearing considering the external load and internal structural parameters is established.
