THE INFLUENCE OF ADHESIVE LAYERS COMPLIANCE ON A RADIAL DEFORMATION OF RUBBER ELEMENTS OF VIBROINSULATORS

摘要

The influence of adhesive layers compliance on a radial deformation of rubber elements of vibroinsulators is considered. The formulas of specific radial deformation for three calculation models of incompressible material's elements under axial compression pressure: solid cylinder, hollow cylinder in a band and hollow cylinder with free side surfaces. The butts of these models are connected to metallic discs with adhesives. Calculation results are presented, some of them are compared with experimental data. It's shown that the influence of adhesive layers compliance on radial strain depends on element's relative dimensions, perforation coefficient and may be important especially for short cylinders. One of the widespread methods of noise and vibration decrease of engineering constructions is using various vibroinsulating and vibrodamping tools (VI). Rubber is usually taken as compliant element's material, ensuring the acoustical efficiency of these tools.
