    Abstract:

    Three kinds of thick leadrubber bearings(TLRB) with different thicknesses of rubbers were designed in this paper. The basic mechanical properties of the TLRB were studied through mechanical properties test, such as vertical stiffness, equivalent horizontal stiffness, postyield stiffness, yield shear force, and equivalent damping ratio. The effects of pressure stress and shear strain on mechanical properties of TLRB were studied. The comparison of mechanical properties between test and formula were analyzed. It is concluded that the difference of vertical stiffness of TLRB between test and formula is apparent and the difference is increasing as the thickness of rubber increases. The fitting formula of vertical stiffness about test was given, and the effect of fitting was satisfying. Because of the limit of samples, the applicability of the fitting formula should be checked in future work. The test value of horizontal properties of TLRB are similar to the formula value.
