摘要: 在传统的静力学鲁棒优化设计基础上，考虑时间t参数，通过优化系统目标函数和约束条件的鲁棒性，将鲁棒优化设计方法运用在动力学问题中。通过一个主系统的质量和刚度均有微小波动的二自由度模型减振器设计算例，与传统的优化设计方法相比，显示了鲁棒优化设计的优越性，能使结构具有更稳定的性能。

Abstract: Based on the traditional robust optimal design in statics, in this paper, robust optimal design is applied to dynamics by considering the parameter t and optimizing the robustness of both the system’s objective function and constraint conditions. Compared to the traditional optimal design’s result in a two-degree-of-freedom system, the robust design of the vibration absorber with mass and stiffness uncertainly in the main system displays a significant improvement in performance.
