Passive vibration control of a satellite boom structure by geometric optimisation using genetic algorithm

, 2003
In this paper, the superior mid-frequency vibration isolation of a geometrically optimized lightweight structure is demonstrated. The initial structure under test here was a 4.5 m long satellite boom consisting of 10 identical bays with equilateral ...

Vertical Random Vibration Analysis of Track-Subgrade Coupled System in High Speed Railway with Pseudoexcitation Method

Shock and Vibration, 2016
In order to reduce the ground-borne vibration caused by wheel/rail interaction in the ballastless track of high speed railways, viscoelastic asphalt concrete materials are filled between the track and the subgrade to attenuate wheel/rail force.

Dynamic Behavior of a Two‐Degree‐of‐Freedom System With Electromagnetic Interaction via a Skew‐Symmetric Matrix

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 579-595, December 2025.
ABSTRACT This paper analyzes the dynamic behavior of a two‐degree‐of‐freedom system subjected to electromagnetic interaction modelled through a skew‐symmetric coupling matrix. The system comprises two mechanically independent oscillators coupled by velocity‐dependent electromagnetic forces.

Multi‐performance‐based optimal design method of locally resonant metastructures for structural control

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 ...

The Modelling and Analysis of Micro-Milling Forces for Fabricating Thin-Walled Micro-Parts Considering Machining Dynamics

Machines, 2022
In the fabrication process of thin-walled micro-parts, both micro-cutting tools and thin-walled micro-parts have the characteristics of small size and low stiffness. Therefore, the regenerative chatter during the machining process cannot be ignored.

Using the inverse finite‐element method to harmonise classical modal analysis with fibre‐optic strain data for robust population‐based structural health monitoring

Strain, Volume 61, Issue 1, February 2025.
Abstract Vibration‐based approaches to structural health monitoring (SHM) gained increasing significance for assessing the behaviour of existing structures because of their non‐intrusive nature and high sensitivity to damage. However, data availability often limits the application of SHM approaches.
