dc.description.abstract |
This article pertains to the prediction of structural vibration frequencies from frictional temperature evolution through
numerical simulation. To achieve this, a finite element analysis was carried on AISI 304 steel cantilever beam-like structures
coupled with a lacing wire using the commercial software ABAQUS/CAE. The coupled temperature–displacement
transient analysis simulated the frictional thermal generation. Furthermore, an experimental analysis was carried out
with infrared cameras capturing the interfacial thermal images while the beams were subjected to forced excitation, thus
validating the finite element analysis results. The analysed vibration frequencies using a MATLAB fast Fourier transform
algorithm confirmed the validity of its prediction from the frictional temperature time domain waveform. This finding has
a great significance to the mechanical and aerospace engineering communities for the effective structural health monitoring
of dynamic structures online using infrared thermography, thus reducing the downtime and maintenance cost, leading
to increased efficiency. |
