- This paper comparatively evaluates measurement-based quasi-linear and true non-linear (mechanical and fluid type) models of hydraulic engine mounts and examines their dynamic effects within the context of a simplified half-vehicle system. A non-linear approximate model is also developed to provide improved insight into the decoupling effects. The proposed model is validated by comparing predictions with those from a “true” non-linear fluid model. When embedded into the vehicle system, hydraulic mount efficiently provides high amplitude-sensitive damping and tunes the engine bounce mode. Proposed model concepts could be effectively utilized to examine linear and non-linear vehicle responses in both time and frequency domains.
