A Survey of Research and Develpment of Hydraulically Damped Rubber Mount of Automotive Powertrain

In this paper, the design and analysis methods for the passive hydraulically damped mount and the powertrain mounting system are reviewed. First of all, the applications of the hydraulically damped mounts are briefly introduced. Then the desired vibration isolation characteristics for the automotive powertrain mounting systems are summarized. Tirdly, the construction principles, discrete parametric models and dynamic characteristics of typical hydraulically damped mounts including simple orifice, inertia track, inertia track-fixed uncoupler, and inertia track-free uncoupler are summarized. Furthermore, the researches on vibration isolation performances and analysis methods of powertrain systems with hydraulically damped mounts are reviewed. The emphases of the survey are on the researches of Freudenberg Corporation in Germany, the Ohio State University in U. S. A., Nissan Inc. in Japan, etc.. Finally, some comments about the future investigations in this field are given as concluding remarks.
