Shock & vibration are unwanted motions required to be reduced, to improve durability of engines and other running machines. Shock and vibration mounting system prevents one object from affecting another. This system are used extensively to isolate machinery (industrial and marine), civil engineering structure (base isolation in buildings, bridges etc.,) and sensitive components from foundation/base. Shock and vibration isolation system reduce the propagation of base vibration to the isolated object and abate the transmission of vibration energy of machinery to the base. In addition to the above, in vehicular, marine & some industrial machines as well as seismic applications, isolators are also expect to lower the impact of shock from base to isolate object and vice-versa. Rubbers being a soft, visco-elastic material have a unique combination of elastic (spring) and viscous (damping) properties makes it such a useful material for vibration and shock mount. Generally S&V mount consists of vulcanized rubber bonded to metal parts facilitating load distribution and installation. For this development work, polyurethane elastomer is used as shock and vibration absorbing part of mount as this polyurethane elastomer can be designed to get better mechanical properties with improved ageing life.
