抄録

As well known, rotating machinery is playing the important role in various industrial fields. Therefore, practical and reliable condition diagnosis techniques for the rotating machinery are essentially important for safe operation of machinery. Since the vibration of rotating machinery in failure condition is controlled by nonlinear dynamics, this paper presents a new diagnosis method in which chaotic dynamics is applied to detect the failure such as cracked shafts of rotating machinery. To verify the diagnosis ability of the proposed method, the numerical simulation for the vibration behaviors of the cracked shaft by using chaotic analysis is successfully performed and proves to be useful.
