摘　　要：文章利用拉格朗日方程建立了弹簧摆运动的动力学方程,并运用Matlab软件进行数字模拟,描绘了悬挂点做匀速运动时弹簧摆坐标随时间变化的演化曲线、运动轨迹、运动相图,分析了其运动情况,得出了更为直观的运动规律。该研究有一定的理论意义和实际价值。This article uses the Lagrangian equation to establish the dynamic equation of spring pendulum, and employs the Matlab software to carry out the numerical simulation. The evolution curve, motion trajectory and motion phase of spring pendulum coordinating with time are drawn and its movement is analyzed to obtain a more intuitive movement law. The research is proved to have theoretical and practical value.
