Determination Of Frequency Dependent Global Dynamic Properties Of Engine Mount

The dynamic properties of engine mount influence the performance of the engine mounting system. The frequency-dependent properties represented the more accurate properties of the engine mount as opposed to the frequency-independent properties model. Impact technique in the past has been used to meas...

The frequency-dependent properties represented the more accurate properties of the engine mount as opposed to the frequency-independent properties model.

In this research, the impact technique is extended to measure the global dynamic properties including the dynamic shear stiffness of the engine mount.. When the engine mount is oriented in certain angles, the combination effect of dynamic compression stiffness and dynamic shear stiffness altered the global dynamic properties of the engine mount.
