Engineering design of rubber pads ageing properties: theory and experiment

The problem of engineering estimation and the current operative analysis for the process of the static and dynamic stiffness changing while considering ageing of loaded rubber pads appeared as the result of mass assembling requirements of vibroprotecting buildings close to the small deep underground lines in Moscow. This problem was solved with the proposed method. Instead of analysis of three-dimensional viscoelastic nonlinear incompressible body, elastomer for example, the design model presenting one-dimensional nonlinear viscoelastic mechanical structure with the parameters taken from experiment was included into design. This model was widely used in the design practice.
