This work focuses on the modeling of elastomeric vibration isolators considering the mass of the bushing. The elastomeric component is represented with the help of a hyperelastic model combined with linear viscoelasticity. The complete experimental and numerical characterization of the industrial elastomeric blend is described, including experimental suggestions and numerical models. Next, the parameters of used models are identified and listed to enable the community to access the model material, characterized with a focus on dynamic loading, easily and quickly. Once the material is fully described two finite element simulations in the time and frequency domain are presented. In the efficient frequency domain simulation, the isolator is harmonically excited, and the simulated dynamic stiffnesses are validated by experiment on the test bench for dynamic stiffness. The discussion of the simulation outcomes deals with the critical aspects of numerical investigation of such dynamic occasions. Lastly, the proposal for future research to solve the issues the work is certainly facing is expressed.
