Engine Isolation Angular Mount with Different Types Elastomers

Abstract

This article was focused on engine isolation elastomeric angular mounts. In ships, submarines heavy machinery is in continuous operations generate massive vibrations and noise. These vibrations and noise will transmit to sea water via machine foundation and will be a passive target for enemies. So it has to be reduced by providing isolation mounts or damping between machines and foundation or source and receiver. For this mounting systems should isolate engine vibrations caused by engine transmits forces in engine speed and prevent engine from shock excitation. This represents that dynamic stiffness and damping of the engine mount supposed to be frequency and amplitude reliant. So making of engine mount has been concerted on developing of frequency and amplitude properties. So different types of elastomeric shock and vibration mounts compounds are developed for two different hardness (45&55) all the mechanical properties ageing properties has been studied and compound with developed NBR, PU& CR compounds of same hardness. In all the cases PU elastomers based compounds are giving better results than NBR & CR. One angular mount is developed its static loads and deflection test at different rated loads has been carried out it gives satisfactory results
