This paper applies a wave guide model to analyze the temperature influence on the dynamic stiffness of a cylindrical vibration isolator of natural rubber in the audible frequency range; covering 20 to 20 000 Hz and - 60 to + 60 degreesC. A nearly incompressible material model is applied with shear modulus based on a fractional derivative model, thereby reducing the parameter number needed to accurately fit measurement results. Employing the method of reduced variables enlarges the frequency range available from measurements. Of particular interest are the stiffness peaks and troughs, the low-frequency stiffness, the propagating and nonpropagating modes, and their dependence on temperature.
