- Abstract
As an important part in vehicle powertrain mounting system, hydraulic engine mounts (HEM) affect the noise, vibration and harshness (NVH) in vehicle greatly. The modeling and parameter identification of the lumped parameters in model has great significance in the design and study of HEM. A lumped model of a hydraulic engine mount based on parameters of the upper and bottom chamber, the rubber spring, the inertia track and the decoupler was established in this study. Then a method to identify the lumped parameters in model was proposed. Finally the results of the dynamic characters by modeling and experiment were compared and analyzed. The analytical methods and conclusions are instructive for the design and tuning of the vibration isolation characteristics of HEMs.
