This section gives information on rubber hardness comparisons and compounds, the principle of anti-vibration mountings, and a brief description of isolation and damping. In addition to this, it outlines basic design aspects regarding the mounting of rubber to metal bonded products, including standard loading directions. It also provides equations for calculating load distribution, a graph showing the relationship between vibration transmission, disturbing frequency and deflection, and finally a couple of examples explaining the basic calculations required for mounting selection.
The hardness of rubber is normally expressed in Shore A. It is determined by measuring the resistance to a cone penetrator.
