摘要
分别使用ANSYS中的拉丁超立方样本蒙特卡罗法、中心复合设计样本响应面法以及Box-Behnken矩阵样本响应面法进行结构可靠性分析和计算.比较分析结果证明,对于静力问题结构可靠性分析,响应面分析结果仅在输出参数的均值、最大值以及最小值上逼近蒙特卡罗法结果,确定目标的可靠度以及输出参数标准差结果偏差较大;对于灵敏度分析结果,仅有高灵敏度变量结果可信.
The strurture reliabiliin resI are analyzed and calculated separately using Monte Carl, sample, response surface analysis method with center romposite design surface analysis method Box-Behnken matrix sample in A NSYS. Th method with sample and analysis resuhs show thal, as to the structure reliability analysis of the static strength, the surface analysis resuh approach the Monte Carlo method result merely at the average values, values and minimum values of output parameters, but the reliability of objective determinatio standard deviation of the output parameter have a big deviation ; as lo sensitivity analysis results vah, es of high sensitivity variables are dependable.
