Estimation of the viscoelastic properties of rubber bushings at very high frequencies (up to 2 kHz) is a challenge
for many damping component manufacturers in the design stage of a quality monitoring procedure. This
investigation is focused on the capability of lower strain rate testing procedures, such as relaxation tests, to
estimate and extrapolate the dynamic behavior of rubber bushings from low to moderate frequencies. Fractional
Zener models are employed to approach bushing behavior in experimental relaxation tests, thus leading to
a linear viscoelastic model which is employed to estimate the dynamic behavior of rubber bushing under
harmonics loads up to 150 Hz. The validation of this extrapolation procedure is performed by comparing these
analytical results with experimental dynamic harmonic tests applied to the same rubber bushings. The deviation
between both curves demonstrates that it is difficult to compare the behavior from very small deformation rates
(relaxation tests) to higher deformation rates (harmonic dynamic tests) due to the nonlinear behavior of the
rubber and its amplitude dependence. However, this investigation demonstrates that the relaxation tests contain
enough data to define the frequency behavior of linear viscoelastic materials up to moderate frequencies
