摘要: 本文先根据韦氏摆振动特点猜想其一种可能的振动模型,再由这种模型写出韦氏摆的动力学微分方程组,然后求解出振动的简正频率和振动的解析解,最后对解析解进行数值模拟并与实验数据进行比对,证明了猜想的合理性.

Abstract:

In this paper,a possible vibration model is conjectured according to the vibration

characteristics of Wilberforce pendulum. Based on this model,the dynamic differential equations of

Wilberforce pendulum are written out. Then the normal frequency and the analytical solution of the

vibration are obtained. Finally,the numerical sim- ulation of the analytical solution is carried

out and compared with the experimental data,which proves the rationali- ty of the conjecture

Key words: Wilberforce pendulum, normal frequency, coupling factor, numerical simulation
