Nondestructive Testing of Welded Test Setup Construction By Vibrational Behaviour
Öz
In this study, the factors influencing the root causes of failure
initiations are examined by conducting the original experimental implementation
and condition monitoring techniques on a welded test setup construction. In
target of root cause failure detection, vibration data are acquired through
radial and axial directions for the analysis. A test setup system has been
designed by gathering inspiration from an existing system in industrial
environment and the test setup constructed by welding method in joinings of
main steel parts. Unbalance and mechanical looseness failures are practised at
one rotation frequency on the test setup. Vibrational data are collected in
three axis simultaneously through four-channel data acquisition card (DAQ)
integrated with the computer system. According to the study results, vibration
analysis in detection of tested failures has been judged to be successful. In
the study, it is mentioned that prognosis and diagnosis may go in incorrect
evaluation respect to the concurrent symptoms of failure data consisting main
orders of the base frequency and natural frequencies that lead to resonance.
