| 摘 要： | 文章首先介绍了响应面法的基本原理,在有限元结构分析的基础上应用响应面法建立了带肋圆柱壳结构的强度失效方程,并将响应面法与一次二阶矩法相结合,解决了参数的当量正态化和独立化问题,最后应用此理论对带肋圆柱壳结构的强度进行了可靠性分析。计算结果表明,基于响应面法的一次二阶矩法具有较好的计算精度。

| Abstract: | In this paper,the fundamental principle of response surface method is studied and the failure equation of ring-stiffened cylindrical shells is established based on the finite element computation results.The random variables are considered to be independent and normalized with the first order method based on response surface.Finally,the reliability of ring-stiffened cylindrical shells with the first order method based on response surface is analyzed.The calculation results indicate that the first order metho... |
