摘要

本文研究了非线性能量汇器件概念的可靠性和鲁棒性。在确定性和概率情况下对系统进行了研究和优化。并研究了不同可靠性的不确定性模型下的鲁棒设计优化公式。所得结果揭示了该装置对输入不确定性的敏感性。用该公式得到的不确定条件下的优化设计与确定性条件下的优化设计有很大的不同。获得了新的系统配置,确保了鲁棒性和高可靠性的设计。并对不同的公式进行了比较,得出了适合该问题的公式。

Robustness and reliability investigations on a nonlinear energy sink device concept
In this work, the reliability and robustness of a nonlinear energy sink device concept are investigated. The system is studied and optimized in deterministic and probabilistic cases. It is also studied under various types of uncertainty modelings with different reliability based robust design optimization formulations. The obtained results reveal the sensitivity of the device to the input uncertainties. The optimal designs obtained with the formulation under uncertainties are very different from the deterministic optimal design. New system configurations are obtained which ensure robust, highly reliable designs. In addition, a comparison is made between the different formulations and a conclusion is drawn about the suitable formulations for such a problem.
