Study on the Influences of the Structural Parameters of Hydraulic Engine Mounts on their Vibration Isolation Characteristics

Abstract:

Hydraulic engine mounts (HEMs) are important vibration isolation parts in vehicle powertrain mounting systems. The structural parameters of HEMs are the main factors which determine their vibration isolation characteristics. It is of great significance to discover the influences of the structure parameters on their vibration isolation characteristics in the design and study of HEMs. HEMs with different rubber materials, lengths and cross-sectional areas of the inertia tracks are designed and manufactured, and their frequency response characteristics are investigated by experimental and analytical methods. The influences of these structural parameters on the vibration isolation characteristics of HEMs are educed. The analytical methods and conclusions are instructive for the design and tuning of the vibration isolation characteristics of HEMs.
