Output-only road roughness identification from vehicle axle accelerations through a universal smoothing method
Zihao Liu, Daniel Dias-da-Costa, Tommy Chan +3
This paper presents an output-only method to identify road roughness profiles from axle accelerations of a moving vehicle. A two degree of freedom half-car model is discretised wit…

A. Calderon Hurtado, J. Xu, R. Salleh +2
Ensuring the structural integrity of bridges is essential for maintaining infrastructure safety and promoting long-term sustainability. In this context, Indirect Structural Health…
Simultaneous Energy Harvesting and Bearing Fault Detection using Piezoelectric Cantilevers
P. Peralta-Braz, M. M. Alamdari, C. T. Chou +2
Bearings are critical components in industrial machinery, yet their vulnerability to faults often leads to costly breakdowns. Conventional fault detection methods depend on continu…
Design of Piezoelectric Metastructures with Multi-Patch Isogeometric Analysis for Enhanced Energy Harvesting and Vibration Suppression
Patricio Peralta-Braz, Mehrisadat Makki Alamdari, Mahbub Hassan +1
Metastructures are engineered systems composed of periodic arrays of identical components, called resonators, designed to achieve specific dynamic effects, such as creating a band…
