In many cases, various mounts are used to support equipment. At the same time, mounts are installed to reduce vibration and noise to and from the equipment. Sometimes, however, mounts unintentionally plays as vibration and noise amplifiers. To study this, an equipment(modeled as rigid mass) with four mounts(modeled as linear springs) are considered. Case studies are conducted with varying stiffness of each mount and varying mass eccentricity. As a first step to reduce transmitted vibration, in this paper, modal analysis has been conducted to find optimum mount stiffness to eliminate directional coupling effect by mass eccentricity is suggested.
