Abstract: Abstract: Hydraulically Damped Rubber Mount (HDM) is widely equipped in vehicle powertrain mounting system and plays an important role in noise, vibration and harshness (NVH) control of vehicle. It is necessary that static and dynamic characteristics of HDM and its effectiveness on vibration isolation of powertrain system are predicted at design and development stage. In this paper, a kind of graphic HDM modeling method integrating with parameter identifications obtained from finite element (FE) analysis and experimental analysis is investigated to predict performance of HDM. The fluid–structure interactions in HDM are explored by predictions of volumetric elasticity and equivalent piston area of fluid chamber using a kind of hydrostatic fluid–structure FE method in commercial code of ABAQUS. Predications of static elasticity and dynamic characteristics and frequency response analysis of a typical HDM with fixed-decoupler verify the effectiveness of the proposed method. This research helps automotive engineers to enhance computer-aided system technology in design and development of HDM and powertrain mounting system. [Copyright &y& Elsevier]
