| 摘 要： | 均匀设计和正交设计在试验次数相近的情况下,前者所选试验点均匀性更好,也更具代表性。该文将均匀设计与响应面法相结合,提出了结构可靠度的数值模拟新方法：基于均匀设计的响应面法、均匀设计响应面与蒙特卡罗抽样相结合的混合模拟法;介绍了利用均匀设计选取试验点构造响应面方程,求解可靠度的流程。结合一个门式框架的可靠度问题,基于AN...

| Abstract: | The chosen experiment points of a uniform design(UD) is generally more uniform and representative than an orthogonal design(OD),even though in the case that the trial numbers of the two experiment design methods are near.In this paper,a new numerical simulation method for structural reliability analyses is firstly proposed,which incorporates a uniform design into the conventional response surface method,herein named as uniform design response surface method(UDRSM).And then,a hybrid simulation method(HSM) co... |
