BASE ISOLATION OF EQUIPMENT AND SYSTEM

The increased dependence of the society on machines provides no room for failure and Inturn demands equipment and systems with higher per- formance reliability. Vibration problems, since decades, have been drawing attention of the scientists and engineers world over to find ways and means to minimise the failures of machines. Though, improvements in manufacturing tech- nology has provided machines with better tolerance and thereby controlled behaviour, the vibration problems are still persisting. Use of isolation devices for rotating machines appears to be a possibility to minimise vibration related problems. An effort has been made in this paper to list down the isolation requirements for rotating machinery both from the point of vibration isola- tion as well as selsmic/shock Isolation. Sallent detalis of a case study regarding base isolation have been presented.
