| Abstract: | The mechanics of circular solid and hollow rubber bearings between two rigid steel plates are considered. The approximately analytical expressions for the axial stiffness and shear strain distribution of the bonded rubber bearing under compression are developed. A three dimensional finite element software (STRAND6) is also used to analyze the characteristics of compression, shear of the circular solid and hollow bonded rubber bearings. Compared the result of theoretical analysis with the finite element result, it shows that the proposed approximate formula for the true Young's modulus is reasonable. |
