Description: Rubber bushes consist of a hollow rubber cylinder bonded on the inside and outside to rigid metal sleeves and are widely used as mountings to provide compliance. Four modes of deformation are commonly defined: axial, torsional, radial and tilting. Formulae, available in the literature for calculating the small strain stiffnesses of such bushes, are briefly reviewed. Sometimes two voids are introduced on opposite sides, running along the length of the bush, to give a directional dependence to the radial and tilting stiffness. An approximate theoretical treatment for such bushes is presented, together with predictions of the stiffnesses from FEA. Mountings in which the inner and outer sleeves are connected by two blocks of rubber, in effect bushes with very large voids, are also considered. It is shown that reasonable predictions of the bush stiffnesses may be obtained from the approximate formulae. Such formulae may therefore be used in design calculations to provide an initial estimate of the required dimensions of the bush and FEA may then be used to refine the initial design.
