AbstractPreceded by unbalance, misalignment is the second most common fault in rotating machinery. The impact of misalignment fault on equipment can be severe and may considerably shorten the machine’s lifetime. This dissertation discusses the unbalance, parallel and angular misalignment forces on rotative machines’ vibration spectra. Numerical simulation model development is used to obtain the time and frequency responses of the rotor-coupling-bearing system. The parallel and angular misalignment response are synchronized with the 1X amplitude of the unbalance displacement. Moreover, the parallel misalignment fault magnifies the 2X amplitude while the angular misalignment response is captured at 2X and 4X amplitudes of the displacement response. Effects of changing the model’s rotational speed, misalignment level, and coupling type are examined for both parallel and angular misalignments.
