摘要
通过实验精准地测量了大摆角情况下单摆的摆角与周期,同时利用Matlab软件,求解了非线性的单摆动力学方程.理论模拟与实验测量的结果进行对比分析,证明了大摆角单摆具有典型的非线性特征.
The angles and periods were exactly measured by experiments in the case of large-angle pendulum.On the other hand,the pendulum kinetic equation was solved by using Matlab.By analyzing and comparing the simulation results with the experimental data,it was proved that large-angle pendulum was typical nonlinear.
