| Abstract: | To analyze the basic mechanical behaviors of rubber isolators,thick rubber isolators of two shape parameters were designed. The basic mechanical properties of the thick rubber isolator in different amplitudes and combinations of frequency were studied through the horizontal shear and vertical compressing tests.The tests show that the basic horizontal mechanical properties are fine and has vertical large deformation. Therefore, the thick rubber isolator is suitable for loading element of new type three dimensional isolated equipment.Furthermore, through the comparison of the basic mechanical properties between the thick rubber isolator and the general rubber isolator, the results show that there is wide difference between the tested vertical stiffness value of the thick rubber isolator and the vertical stiffness got from the general theory formula, and little difference in the level stiffness. |
