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.

Adaptive Feedforward Vibration Control of Helicopter Cabin Floor Driven by Piezoelectric Stack Actuators: Modeling, Simulation and Experiments

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Active control of structural response is the most practical and effective approach to mitigate helicopter vibration and enhance ride quality. In this paper, adaptive feedforward vibration control is constructed for the helicopter cabin floor driven by piezoelectric stack actuators (PSAs).

Closed‐Form Design and Understanding of Vertical Inerter–Based Dampers for Wind Turbines

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Wind turbines with larger capacities face bending deformation due to taller towers and longer blades, necessitating mitigation against extreme seismic loads. A vertically installed inerter‐based damper, referred to as the tuned viscous mass damper (TVMD), is proposed alongside a closed‐form design approach.

Bridge Flutter Prediction and Active Control Using Modal Information and Flutter Margins

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
In this paper, a flutter prediction method based on flutter margins is proposed for streamlined bridges whose aeroelastic behavior can be well approximated by a two‐degree‐of‐freedom (2‐DoF) flutter model. The method enables prediction of the flutter boundary by extrapolating a curve of flutter margin versus wind speed, constructed using flutter ...

Automated Transmissibility‐Based Damage Detection for Output‐Only Systems

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
In this study, an automated transmissibility‐based procedure for damage detection is developed for output‐only systems. The application of transmissibility has been previously investigated for damage detection. Despite the advancements, current techniques are not applicable in a general way, as vast experience or expert knowledge is needed to achieve ...

Estimation of Joint Parameters Using Frequency‐Based Substructuring Techniques

International Journal of Distributed Sensor Networks, Volume 2024, Issue 1, 2024.
This study presents frequency‐based substructuring (FBS) techniques and an identification method for predicting joint parameters. Two FBS techniques, FBS‐1 and FBS‐2, were derived by assuming pseudomasses at the joint nodes between adjacent substructures.

Receptance coupling for dynamics prediction of assemblies with coincident neutral axes

Journal of Sound and Vibration, 2006
This paper details the prediction of flexural receptances for nested components with common neutral axes using a multiple-point receptance coupling approach. Numerical validation is included for different numbers of coupling coordinates, equal and unequal coordinate spacing, rigid and finite stiffness component connections, and component interface ...
