【 摘 要 】

Linear spring mass framework controlled by moving belt friction have been subjected to various examinations. Dynamical attributes like amplitude and frequency of oscillations have been in a big way studied along by the whole of the different approach mechanisms for this model. Along by all of the dynamical characteristics, bifurcation structures also have been investigated. On the other hand, the corresponding self-excited SD oscillator has not instructed comparable attention. This complimentary presents the numerical investigation of the character of a self-excited SD oscillator resting on a belt moving with consistent speed and excited by dry friction. The moving belt friction is displayed as the Stirbeck friction (friction first decreases and then increase smoothly with interface speed) to figure the scientific model. It is demonstrated that the pure-slip oscillation phase influenced by system parameter α. The influence of different system parameters on the dynamical characteristics was alongside considered.
