Discrete Dynamics in Nature and Society, Volume 2021, Issue 1, 2021., 2021 Urban rail corrugation on curved tracks with small radii causes strong howling during operation, which has been bothering subway operating companies for many years. Therefore, revealing its causes and growth is important for the comfort and safety of subway operation. Current studies believe that the occurrence of rail corrugation is largely due to the

Optimization and Tuning of Passive Tuned Mass Damper Embedded in Milling Tool for Chatter Mitigation
Journal of Manufacturing and Materials Processing, 2020 Milling tools with a large length–diameter ratio are widely applied in machining structural features with deep depth. However, their high dynamic flexibility gives rise to chatter vibrations, which results in poor surface finish, reduced productivity ...

Shock and Vibration, Volume 2020, Issue 1, 2020., 2020 Vibrations due to mechanical excitation and internal and external fluid flow can cause fatigue in pipelines and leaks in fittings. A beam‐based dynamic vibration absorber (beam DVA) is a device comprising an L‐shaped beam with a concentrated mass at its free end that can be used to absorb and dissipate vibrations in the pipeline.

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 25, Page 4193-4211, 20 October 2025.Abstract Locally resonant metamaterials (LRMs) have been extensively investigated for wave attenuation; however, the interaction between their bandgaps and a structure's modal dynamics remains relatively unexplored. To address this gap, a design framework is presented to quantify and enhance the structural control performance enabled by LRM‐induced ...
