Presented paper deals with determination of dynamic stiffness of rubber bushing. Viscoelasticity of rubber is introduced. Next rheological models are shown and determined. Theory of the viscoelastic constitutive relation are done with storage modulus and loss modulus. Rubber bushing FEM model was prepared for calculation of dynamic stiffness through dynamic harmonic analysis in MSC Marc. Results from simulations are compared to experimental measurement data.
