Abstract
In a hydraulic mount the use of multiple primary orifices with unequal area reduces the effects of rapid transitions in dynamic rigidity and the amplitude of impulsive vibration generated thereby. This invention's reduced impulsive vibration has lead to the substantial elimination of mode transition related noise in associated vehicle structures in the 200 Hz to 500 Hz range.
