Stiffness simulation analysis of rubber bush mountings

The finite element model of rubber bush mountings based on ANSYS is built up. And the value of the reduced radial stiffness is obtained directly by solving the model. The analysis of the experimental data, the theoretical calculation data and the simulation data indicates that the simulation model of the rubber bush which has been established is correct. Based on the simulation model, which has been parameterized, the radial stiffness characteristics of rubber bush are studied by analyzing the influence of the axial length and the Poisson's ratio on the reduced radial stiffness. It is shown that the influence of the axial length on the reduced radial stiffness of short rubber bush is great and the influence of the Poisson's ratio on the reduced radial stiffness of long rubber bush is great.
