Dynamic responses assessment in fault diagnosis of multi-function active engine mounts with cooling capacities

Engine mount is one of the most significant joints in vibration isolation in diverse vehicles which reduces the effects of two important sources of vibration (i.e. road and engine) with extremely different features in frequencies and domain. Nowadays, most of vehicles companies are considering to new engine mount with adoption control methods due to their tendency to the light vehicles with minimum noise and vibration. Electro-magnetic engine mounts are among these active mounts which considered in the recent years. Vibration analysis is one of important techniques in fault detection and condition monitoring. Due to this fact, in this study with application of dynamic responses and frequencies responses diagram, significant results in fault detection in electro-magnetic active engine mount system, it's life-time increase, and repairing cost decline, will obtain. In order to achieve these purposes, after introduction of the engine mount structure and system modeling, different faults especially those caused by thermal and corrosion interactions have been introduced. Finally, qualitative and quantitative states of both separate and combined fault diagnosis systems will be presented. According to these tables, six separate faults and three combined ones will identified.
