摘要
在分析对称双弹簧振子横向振动特点的基础上,根据极限情况下方程解的性质,提出双弹簧振子横向振动微分方程的近似解析解,并得到了横向振动周期的具体表达式;通过与数值解结果的比较,说明近似解是有效的.
The analytical approximation of the differential equation of transverse vibration has been proposed by analyzing its characteristics.And the specific formula of the period of transverse vibration has been obtained.The approximate solution is proved effective by comparing with numerical result.
