弹簧质量对振子运动的影响

The effect of mass on the motion of Oscillator

弹簧振子是物理学中的一个典型模型,在实验中得到的弹簧振子的振动频率和理论结果存在着较大的差异,其中有很多原因,但主要是由于弹簧的质量对振动有一定的影响。通过四阶龙格—库塔法,求解含质量的弹簧振子运动方程的解,由计算结果分析弹簧质量对系统振动频率的影响。

Oscillator is a typical model in physics.We have found that there are many differences between the experimental result and the theory about stiffness frequence.Though there are many reasons,the main one is the effect to the stiffness by the quality.This paper will adopt four bands Runge-Kutta method to solve the result of the equation on motion of oscillator,and analyze the effect to the stiffness by the oscillator quality.
