- The modern industrial system is built on rotating machinery. Faulty machinery significantly increases vibration, particularly in the coupling, which leads to catastrophic failure of essential machinery components and, in some cases, worker life. As a result, the fault-free operation of rotary machinery with proper alignment is the primary goal of many companies. This study attempts to establish a relationship between the amount of misalignment and the rise of vibration amplitude at pertinent coupling frequencies. For this purpose, an experimental setup was designed and developed. Also, the experimentation was carried out to predict the vibration amplitude by considering various independent variables like speed, mean bearing radius, misalignment tolerance, mass moment of inertia, moment of area, modulus of elasticity, and weights of various coupling, rotors, load drum, and shafts. The effects of these various independent variables have been portrayed in terms of a group of pi terms with the help of the dimensional analysis technique. The model for vibration amplitude was formulated by using these pie terms. A further developed model was analyzed qualitatively and quantitatively. The reliabilities of mathematical models obtained are practically superior. However, some pie terms in the mathematical models are highly sensitive whilst others are less sensitive.
