摘要
提出了求解非线性方程组的一种有效方法——变分迭代算法。这种方法的基本特点是引进若干拉氏乘子校正其近似值，而拉氏乘子可用变分的概念最佳识别。应用这种方法，我们分析了平面二簧系统的静力逆问题。
In the paper, a new method called variational iteration method has been proposed to solve nonlinear system of planar 2 spring in inverse force analysis. With such method, a more accurate solution can be obtained by successive correction to its approximation by means of Lagrange multipliers, which can be identified by making the correction equations stationary
