摘要
对强非线性振动系统进行参数变换 ,把强非线性振动系统转化为弱非线性振动系统 ,同时再把振动系统的解展开为付立叶级数 ,利用参数待定法即可方便求出强非线性振动系统的高精度摄动解。
The parameter transformation is carried out on strongly nonlinear vibration system,which is transformed to weak nonlinear vibration system,and the solution of vibration system is expanded Furier series,the approximate solution of strongly nonlinear vibration systion is found easily by parameter undeterminated method.
