✦ Synopsis
For the rolling slipping state of a main drive system, the present paper established the nonlinear mechanical model of the main drive system and used the Krilov-Bogolubov method to produce the solution of the nonlinear mechanical model, and ascertained the condition of generating self-excited vibration. It also presented a method of calculating the upper and the lower limit angular velocities between which self-excited vibration of the main drive system occurs. A relationship of rolling force, friction coefficient between rool and rolled piece, and rolling angular velocity was derived to judge whether self-excited vibration happens or not. The method may provide a valuable way to avoid self-excited vibration and thus prevent the instantaneous breakage of the system due to the self-excited vibration.
