Abstract
The relation between applied force and deflexion for bonded cylindrical rubber bush mountings of various dimensions is investigated theoretically and experimentally for four principal modes of deflexion. For symmetrical deformations of the elastic material, a theoretical treatment based on the classical linear theory of elasticity is found to predict adequately the variation of stiffness with bush length. In the case of unsymmetrical deflexions the theoretical treatment is limited to the derivation of approximate values for the limiting stiffnesses for long and short bushes. These theoretical values of limiting stiffness are compared with the values measured experimentally.
