A Study on Mode Shape and Natural Frequency of Rotating Flexible Cracked Annular Thin Disk
Figure 6
The effect of vertical crack on the vibration characteristic of flexible cracked disk: (ai) the natural frequency curve of the flexible annular thin disk with long cracks, and i = 1, 2, (a1) CF-crack, (a2)TG-crack. (bj) The eighth modes of the flexible annular thin disks with long cracks, and j = 1, 2, 3, 4, (b1) CF-crack with a span angle of 80° (CF80), (b2) CF-crack with a span angle of 100° (CF100), (b3) TG-crack with a length of 40 mm (TG40), (b4) TG-crack with a length of 48 mm (TG48).
