Hydraulic engine mounts isolate the structure of the vehicle from powertrain vibrations and also prevent excess motions of the powertrain due to shock excitations. In this paper, dynamic stiffness of a hydraulic engine mount in low frequency range (shock frequency range) is predicted using modal test data and three-dimensional finite element model through an iterative model updating procedure. The implemented model encompasses elastomeric material’s nonlinearity, fluid-structure-interaction and internal resonances of mount. Mesh morphing technique is used to model the fluid-structure-interaction. The results showed that the introduced procedure can successfully predict the shock isolation behaviour of the hydraulic engine mount.
