应用响应面结合空间映射方法的可靠性评价

Reliability Evaluation on Applying the Method of Combining Responsive Plane with Space Mapping

应用响应面结合空间映射方法,在第一次迭代拟合极限状态函数,其它迭代应用映射技术在第一迭代响应面基础上映射调整得新得极限状态函数,并进行可靠性分析。方法改变了序列响应面方法评价可靠性时需要反复对模型进行试验设计、分析并拟合极限状态函数得执行过程,从而大大降低了模型分析的计算量。

The method of combining response plane with space mapping is applied to the first iteration so as to fit the ultimate state function. On the other hand, the mapping technology is used at other iterations so that the new ultimate state function is obtained from the mapping adjustment based on the response plane of the first iteration. And then the reliability analysis is carried out according to the above. This method has changed the reliability evaluation method of the sequence responsive plane, which needs repeated experimental design, analysis and fitting the operation process of the ultimate state function for the models, thus reducing the calculating amount of the model analysis greatly.
