Abstract: High-speed rotor systems involve numerous degrees of freedom and is constrained by computational time and cost. Generally, the rotational degrees of freedom (DOFs) are omitted and the active DOFs are chosen arbitrarily. This study aims to reduce the model by gradually discarding the translational DOFs and investigate its effect on the response of complex high-speed rotors. A set of recommendations are suggested for careful selection of the DOFs at important locations, which influence the reduction success chances. Though the reduction methods are found in the literature, the reduction in translational DOFs and its application to different high-speed rotors is completely new. This is important because these high-speed rotors are complex in design and susceptible to rigorous vibrations and instability. [ABSTRACT FROM AUTHOR]
