Abstract
In this paper, the authors presented various insights into theoretical and experimental analysis carried out in past, to understand the vibration characteristics of a misaligned rotor-bearing system. The literature presented by various researchers was reviewed methodically. Firstly, the literature review based on theoretical vibration analysis of misaligned rotor system with emphasis on finite element method has been presented. Secondly, various vibration-based analysis methods and the description of experimental measurement techniques have been discussed in detail. Apart from the above, distinct tools used for the detection of fault analysis of the rotor system is also reviewed systematically, which may be useful for preventive maintenance of the rotating machinery used in several industries.

Coupling misalignment is the most common fault that occurs in a rotor-bearing system
The objective of this paper is to study numerous analysis models used for the dynamic analysis of a rotor-bearing system with coupling misalignment
As many researchers perceived that second harmonic response gives a strong signal for the misalignment of the shaft, literature shows that other types of rotor system malfunction can produce second harmonic response such as rotor friction or rotor cracks
Summary
Coupling misalignment is the most common fault that occurs in a rotor-bearing system. Mechanical alignment couplings gear or grid coupling, impose a bending moment on the machines, which is the function of the transmitted torque. A lot of research has been performed to interpret the vibration response behaviour of a rotor-bearing system. It is evident from the available literature that the first harmonic response is due to the presence of unbalance in the rotor system.
