摘要
研究了一类具有非线性阻尼力和强迫周期力项的相对转动扰动动力学方程.首先利用变分原理构造了广义变分迭代,其次决定方程的初始近似,最后通过迭代表示式得到了对应方程的任意次近似解.
A class of relational relativistic rotation nonlinear disturbed dynamical equations possessing nonlinear damping force and forcing periodic force is investigated. Firstly, by using the variational principle, the generalized variational iteration is constructed. Then the initial approximate solution is determined. Finally, by using the iteration, the approximation to an arbitray degree for corresponding equation is found.
