     the validity of the widely-quoted experimental data for the reduced radial stiffness of a cylindrical rubber bush mounting of finite length is discussed by proposing an analogy between such a bush and two tandem cylindrical rubber blocks of circular cross-section which are axially loaded. previously-derived expressions for the radial stiffness of a finite-length cylindrical bush and the apparent young’s modulus of an axially-loaded bonded rubber block of circular cross-section are exploited. this leads to an adaptation of the data that incorporates the possible failure of the bushes due to internal rupture. the analytically-derived values of this stiffness are demonstrated to have improved agreement with these appropriately modified data. representative numerical results are presented for a range of bushes in tabular and graphical forms.
