    Abstract: How to improve the robustness of structural dynamic performance, and how to minimize the influence of various uncertainties on mean design are one of the hot issues both in academic and engineering fields. In this paper, the basic concept of structural dynamic robust optimization design is described. The robust optimization design methods of structural dynamics are reviewed from three aspects that are based on Taguchi method, multi-objective optimization and response surface methods. Taking a dual-rotor as an example, the dynamic robust optimization design is carried out by using the response surface modeling and multi-objective optimization methods. The results show that multiple robust optimization design schemes can be obtained based on response surface modeling and multi-objective optimization, and robust design methods have great potential for application in structural dynamics to deal with uncertain problems. Finally, the current research methods and future work are briefly summarized and prospected.
