【Abstract】 For a new type of instrument used for showing precession of stiff body in teaching activity,the dynamical model is modeled to study the mechanism of its dynamical phenomena. By analyzing the bifurcation of its transient equilibrium, it is found that the reason of the standing up phenomenon is that the system has stable transient equilibrium near to π2 while the two possibilities for the gyroscope to tilt inward or outward is due to the bifurcation of the transient equilibrium.更多还原
