【Abstract】 Stability of periodic impact motion between the vibration screen and single particle is investigated by establishing the mechanical model of relation between the vibration screen and single particle.It is demonstrated that the system can exhibit chaotic behaviour via periodic bifurcation and doubling-periodic bifurcation of periodic impact motion of single particle.Route from periodic bifurcation and doubling-periodic bifurcation to chaos is discussed.The system parameters of the vibration screen may be optimized by studying the stability of periodic impact motion of single particle.更多还原
