Description
Of the many methods of introducing damping in
vibrating structures, the dissipation of energy due to
interfacial slip can significantly increase the damping loss
factor. However, because of the lack of understanding and
other phenomena such as fretting corrosion and loss of
structural rigidity, friction damping is rarely used. A
study was thus undertaken to investigate this complex
phenomenon, with emphasis on trying to gain a better
understanding of friction damping with certain parameters
such as clamping pressure, frequency, magnitude of
excitation and surface finish. Although the non-linearities
associated with friction makes this mechanism difficult to
model mathematically, finite element (FE) analysis shows
some promise. Although the results obtained using an FE
model were not exactly comparable to the experimental
results, these analytical results did show the same general
trends as observed in the experiments.
