Abstract : In this study, a servomotor driven coupled elastic shaft-elastic beam system is analyzed. The model consists of a servomotor, disk, and an elastic beam attached to the disk separated by an elastic shaft. This mechanism has considerable applications in the industry and can be present in vehicles. Equations of motion are derived with respect to the generalized coordinates of the elastic shaft, elastic beam and the servomotor rotation. Frequency equations and mode shapes for the elastic beam and elastic shaft are obtained assuming compliant boundary conditions. Nonlinear terms which come from the Coriolis, normal and tangential accelerations are retained in the equations. The eigenvalues of the relatively elastic shaft-elastic beam system and relatively rigid shaft-elastic beam system are analyzed with respect to the desired control frequencies and dampings of the servomotor. The system has three complex pairs corresponding to the beam natural frequency, torsional natural frequency and actual servomotor control frequency and damping. Actual control frequencies steadily increase and reach to an asymptotic value that is the torsional natural frequency of the shaft-disk system while the actual control damping steadily decreases to an asymptotic value of the viscous damping of the elastic shaft. Torsional natural frequency of the motor-shaft-disk system branches into real roots at a certain desired control frequency. Beam natural frequency is not altered by the desired control frequencies and/or dampings
