An new method for selecting sampling points in response surface method;
一种在响应面法中选取样本点的新方法
The response surface method (RSM) for structural reliability analysis is improved by proposing a new strategy for positioning sampling points.
在以响应面法分析结构可靠度中,提出了一种区别于通常以插值点为中心展开生成样本点组的新方法:在求解过程中,用插值点逐步替代初始样本点组中距离验算点较远的点,目的是使所选取的样本点集中于真实极限状态曲面上的验算点附近,重新构成下一轮迭代所需的一组样本点,直至满足收敛条件。
