Abstract: This paper reviews and collates the information required to achieve effective vibration isolation with rubber components. The emphasis is on recent developments and high-frequency performance. As a rule of thumb, rubber components are especially suitable for reducing transmission of audio-frequency vibrations. Such rules are put on a rational basis, by relating transmissibility to the density, modulus and damping of the rubber and to the geometry of the mount. This enables the most appropriate rubber for a particular job to be chosen from the wide range available. The relevant properties of representative rubbers are given and discussed. The use of compound isolation systems and the treatment of non-rigid foundations is most efficiently handled by the four-pole parameter formalism which is briefly introduced. This formalism also suggests the measurements which are required to characterise the high-frequency performance of a rubber component.

Keywords: audio-frequency vibrations; compound isolation systems; damping; finite element analysis; FEA; rubber components; transmissibility; vibration isolation.
