摘要
可靠度响应面有限元是可靠度计算与响应面有限元的直接耦合 ,是采用有限元数值模拟来解决功能函数不能用解析式表示的结构可靠度问题的一类方法 ,对于大型复杂结构的可靠度分析有重要的意义。本文简述了响应面方法的研究发展 ,给出了可靠度响应面有限元的几类算法和可靠度计算的两种途径 ,并介绍了响应面有限元方法在实际工程中的应用情况。
Reliability response surface FEM method is a direct coupling of reliability calculation with re sponse surface FEM, which can solve the reliability problems with the closed formed performance function in actual engineering based on FEM numerical simulation. Various version of reliability response surface FEM are comprehensively discussed. The reliability calculation based on response surface FEM and the application of the response surface FEM are reviewed.
