Dynamic behavior comparison of passive hydraulic engine mounts. Part 2: Finite element analysis

This paper investigates the applicability of nonlinear finite elements to the difficult task of parameter identification of the structural behavior of passive hydraulic engine mounts. By using hyperelastic constitutive relationships the incompressible nature of the rubber materials that make up the bulk of the engine mount are accurately described and the results of such analysis are used directly in previously developed lumped parameter models to fully describe the dynamic behavior of two distinct hydraulic engine mounts.
