Abstract: In this study, an angular momentum generated by a flywheel gyroscope is performed as a suspension to prevent vehicle vibration. The frequency equations are derived and the optimal flywheel speed is obtained for vibration attenuation of the sprung mass. It is observed that the control moment gyroscope (CMG) keeps the sprung mass in the upright position with a small vibration amplitude of a steady motion. The flywheel speed (Ω) is in relation to the amplitude of gimbal motion and the frequency (ω) of the axle's excitation. Besides, a simulation model of CAE software (RecurDyn) is built to validate the equations of motion.
