Abstract
In order to analyze vibration modes and resonant frequencies of a mechanical structure system in good accuracy, the interface contact stiffness becomes important. In this study, the technique which efficiently calclates the contact stiffness is proposed. Proposing method uses design of experiments and response surface methodology, and furthermore, to improve accuracy of identification , uses sequential linear programming while considering both natural frequencies and vibration modes of a system. In this paper, the effectiveness of proposing method is verified by numerical simulation taking a simple example.
