Dynamic Analysis of Transmission Gears With Combined Tooth Wear and Root Crack Failures

open access: yesShock 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

open access: yesShock 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.
