Multigrid method based on nested iteration methods for elastic beam dynamic response analysis

提出了一种基于套迭代技术的求解弹性梁动力响应的多重网格方法。这种方法充分利用了初始网格下的结果,然后由多重网格嵌套迭代过程实现对弹性梁动力响应问题的求解。这种方法将网格离散过程和数值求解过程很好地相结合,与其他方法相比较,具有计算精度高,运算时间短等特点。

An multigfid method based on nested iteration methods is described for solving elastic beam dynamic response. The method utilizes sufficiently the resuits in the original meshes and accomplishes the solution of the elastic beam dynamic response problems by multigrid nested iteration procedure. The method combines the grid discretization with the numerical solution. The numerical results show the high efficient and high precision of the method as compared with the other method.
