Abstract

This paper aims to present a method of detecting deterioration on rotating machinery in the
form of Machinery Fault Simulator (MFS) performed in the lab. The study enhances the knowledge of
signal pattern of misalignment phenomenon as compared to baseline signal pattern obtained from
normal condition of rotating shaft. The focus of this experiment was on misalignment problem. There
are two types of misalignment which are parallel and angular misalignment. Input in frequency was
selected for motor movement and the shaft start to rotate. The vibration signal from the shaft was
acquired using in built tachometer in the MFS. In this experiment, data shows that the vibration occurs
in different shape of the amplitude at different speed of the angular motion. In baseline test, the
amplitude values are fluctuated at every accelerometer channels. Meanwhile, the amplitude on the
angular test shows that the amplitude is higher at axial axes only compared to both axes. Meanwhile,
for the second test, the angle of 15o
was applied at inboard in the system caused to the misalignment of
the shaft. In vibration analysis, the misalignment of the shaft was detected from the changes of the
amplitude at three different axes. Copyright © 2016 Penerbit Akademia Baru - All rights reserved.
