Design and Evaluation of a Compact Vibration Isolator for Use In Retrofit Telecommunications Fan Unit Applications

Abstract

Fan vibration has become a significant issue in telecommunications environments due to increased performance and heat of internal components requiring greater airflow and higher speed fans. This thesis investigates fan vibration problems in telecommunications equipment and develops solutions to the problem in a retrofit scenario. A target value for vibration levels was determined by measuring vibration levels in an alternate existing product that exhibited no wear issues over a span of several years. Two successful vibration isolator designs were developed and implemented. The retrofit solution required minimal changes to the legacy design and achieved a large vibration reduction. The ultimate solution required extensive changes to the legacy design and achieved significant vibration reductions, with vibration levels below the target value in most scenarios. Both designs are Patent Pending.
