Abstract：Radial damping hydraulic bushing is the object of this study, which is widely used as vibration isolator in the vehicle chassis system. The lumped parameter (LP) model for hydro-bushing is usually applied to the dynamic characteristic analyses. Two-way fluid-structure interaction FEA (nonlinear finite element analysis) technique is used to identify the main parameters of the LP model. The FEA method also can be applied to calculating the dynamic characteristic of hydraulic bushing. Comparing the calculated results with the experimental data and numerical prediction results, the feasibility and accuracy of the FEA method was confirmed. The method proposed in this paper can ensure high quality and low cost in hydraulic bushing development.
