Abstract

Vibration that occurs in most machines,structure and dynamic system is undesirable that may lead to fatigue and failure of structure and machine,energy losses and the reduction in performance of structure or machines. The vibration effect to a structure is usually not be detected at early stage and main reason lead to collapse building.The factors are mostly because of poor or no isolation from the vibration sources to the attached structure.The custom-built test rig for faults detection is readily available but limited for example because of cost,too huge,heavy and complex to control.The purpose of this project is to design and to fabricate a simple test rig to verify the performance of looseness,unbalance, transmissibility and resonance based on the experimental data by using vibration analysis.The test rig also was built for teaching and learning purpose.Therefore,it was design to make lifting easier and can be placed anywhere especially can be bring to class for teaching and learning purpose.In this project,induction motor was used as important component in test rig to represent the failure in structural that occur.The vibration experimental test rig was designed by using SolidWorks 2013 software.Then,it was fabricated based on desired dimension before undergo testing process.For testing process,the test rig was analyzed using Data Physics SignalCalc Ace.The finding shows that the performance of unbalance and looseness can be verified when compared it with normal condition of induction motor when the vertical peak shows obviously different value especially for unbalance condition with the value 0.003004 (mm/s)2 .The value for unbalance faults is higher compare to looseness and normal condition.The finding also shows rubber can be a good isolator or shock absorber in transmissibility experiment but also can be vibration problem if the stiffness of isolator,the mass of the isolated equipment and the running frequency is not consider.
