Vibration Isolation Analysis: Elastomers and Low-Carbon Steel March 7, 2008 By Nathan Quinn EMA 303 Discussion 302 Abstract The analysis described in this document details the requirements and results of the analysis of a vibration isolator. The shear modulus and allowable shear stress of the elastomer to be used were given, as well as the allowable shear stress in the bonding material used to bind the elastomer to the low-carbon steel housing and rod. The goal was to find the dimensions needed for the elastomer so as to not violate the allowable stresses. The stresses were based on a 700 N axial force applied in tension to the steel rod. Also taken into account was the volume of the steel and elastomer, as these affect the cost- effectiveness of the design. The final dimensions of an inner radius of 19.60 mm, an outer radius of 39.22 mm, and a height of 7.11 mm were based on these considerations. Introduction Vibration in a component or group of components is a major component of the lifespan and efficiency of these items. The ability of certain materials to absorb the deformations caused by vibrations without failing themselves enables other components in the system to function without being subjected to stresses that would cause them to
