“…First, the results of the experiment conform to those determined by the AMM and FEM. Second, the method utilized cannot completely display flexible disk frequencies of the system and in the detail found in Chiu et al, 29 for example, 1a (except 1a 21 ) and 1b modes.…”

“…From Chiu et al 29 and from comparison with Table 6, the frequencies of the third peak (near 81 Hz) are the blades' first mode guides. The second peaks (near 70 Hz) are the cracked-blade mode guides (1a 21 , 72.56 Hz). From Chiu et al, 29 the first peak is the support frame.…”

“…Chiu and Huang 20 explored how a crack affects these three types of coupled-vibrations type tuning a shaft-flexible disk-blade system. Recently, Zhou et al 21 and Chiu et al 22 used the FEM to investigate a single-/multi-flexible disk rotor with springs and compared their results with earlier research results.…”

Based on previous research results obtained in the authors' laboratory, in this article, we develop, refine, and summarize the disk-transverse, blade-bending, and shaft-torsion coupled-vibration phenomena of a multi-disk rotor with blades with multiple cracks. Three methods are used to explore these phenomena, namely, the finite element method, experimental method, and assumed mode method. The assumed mode method is primary, and the others play subsidiary roles. Some beneficial and interesting results are presented in this article. First, the authors used the assumed mode method and finite element method (ANSYS) to explore and compare the change rules of the natural frequencies and mode shapes in a rotor. Second, it is pointed out how multi-cracks affect the coupled-vibration phenomena of a single-/multi-disk(s) system. Numerical calculation results also show that the crack depth, number of crack blades, as well as the symmetry of the crack blades, affect the natural frequencies. Finally, the experimental results are discussed and the advantages and limitations of using each of the three methods are given. While the experimental measurement method advanced herein may have some limitations, the results should guide future research.
