説明

It is known that, under appropriate conditions, the amplitude of vibration of some blades in the mistuned bladed disk system become large compared to what would be predicted by an analysis of a perfectly tuned system. In this paper, the rms responses of the mistuned bladed disk system subjected to deterministic excitation and random excitation with the spatial correlations are investigated. Because the mistune arrangement effects the rms response of the mistuned system, the rms response of all mistune arrangements are calculated in case that number of mistuned blades is 8. In the case of the large and small rms response, the effect of the ratio of amplitude of the deterministic and the random excitation on the averaged wave number components of the mistuning arrangements is discussed. It is shown that the averaged wave number components when both the deterministic and the random excitations act simultaneously differs from that in the case that both act individually. It is also noted that those averaged wave number components of the mistuning arrangement do not change linearly to the ratio of amplitude of the deterministic and random excitation.
