ABSTRACT:
Each bearing of an aligned line-shaft has vibration responses which differ from the vibration responses of a misaligned system in which at least one of the bearings is statically displa=ced. Computed static displacement values for each bearing are derived from the equation of motion of the system employing mass, stiffness and damping coefficients of the system. The static displacement value of each bearing is computed from the vibration responses of all of the bearings. Accelerometers sense the vibration response of each bearing. A computer computes the magnitude of misalignment of each bearing from the sensed responses. The computed results provide an indication of the magnitude of static displacement of each bearing of the system causing the sensed vibration response.
