为了提高设计结果的置信度,降低实验成本,提高计算效率,提出了基于时变并行可靠性的设计优化方法。首先通过发展的方差函数分析选择敏感的时变设计参数。然后,通过构建实验误差函数以及实验与计算机模型之间的均值函数,对敏感设计参数进行验证。然后确定子域,最后基于MCS方法构建并求解基于时变并发可靠性的设计优化。通过一个案例分析,说明并验证了我们所提出的方法。
This paper presents new time-dependent concurrent reliability-based design optimization methods for improving the confidence of design results with reduced experimental cost and increased computational efficiency. The sensitive time-dependent design parameters are first selected through the developed functional Analysis of Variance. The sensitive design parameters are then validated by constructing the experimental error function based on experimental data, and the function of the mean between experiments and computer models. The sub-domains are next determined, and the time-dependent concurrent reliability-based design optimization is finally constructed and solved based on the MCS method. A case study is used to illustrate and testify our proposed methods.
