Chapter hvac engineering Fundamentals: Part 1 Introduction

20.6.3
Vibration transmission and isolation
The simplest way to minimize vibration transmission is to isolate the
machinery that causes the vibration. This is done by means of flexible
isolators, often combined with inertia bases. A flexible isolator is most
often a spring. For less demanding applications, it may be a block of
cork or rubber, or a rubber-in-shear device, in which the rubber is used
as a spring. In general, the best isolation is provided by the ‘‘softest’’
support, allowing the vibrational energy to be dissipated in movement.
