APPLICATION OF ROBUST OPTIMAL DESIGN IN STRUCTURAL DYNAMICS

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.
