															Abstract:  
	The nonlinear dynamics of a simple pendulum is solved using lagrange equation,and the numericalsimulation is carried out with Python software. The influence of damping factor and torque drive on the motionof simple pendulum is investigated. The simulation results present the variation of the pendulum angle andangular velocity with time, the evolution of the phase trajeetory, and the chaotie phenomenon under strongdriving foree.
