An ideal vibration isolation system should have low transmissibility, extensive isolation range, and stiffness to support any static load. Isolators are designed and developed for various applications where vibrations in the system become a bane to it, we find that most of the isolators use rubber as an electrostatic element while other designs also adopt wire rope and springs. The spring-type isolators are metallic and offer better flexibility in addition to the longevity of their performance as rubber loses its elasticity over the period. Helical springs are extensively used in many applications where the isolator is intended to perform for longer periods. In this paper, we present a detailed design and analysis of the metallic spring conical isolator that finds its application in airborne systems.
