摘要
在用直接积分法求解非线性结构的动力响应时,常常需要做迭代运算。本文引入摄动方法后,加快了收敛速度,提高了计算效益。
It is used to make iterations to solve dynamics responses of nonlinear structure by direct integration methods. After perturbation methods is introduced by the paper, convergence has been speeded up and computation efficiency has been advanced.
