The influence of shaft bending on the coupling vibration of rotor-blades system is nonignorable.
Therefore, this paper analyzed the influence of shaft bending on the coupling vibration of rotor-blades system.
The vibration mode function of shaft under elastic supporting condition was also derived to ensure accuracy of the model as well.
The influence of the number of blades, the position of disk, and the support stiffness of shaft on critical speed of system was analyzed.
The numerical results show that there were two categories of coupling mode shapes which belong to a set where the blade’s first two modes predominate in the system: shaft-blade (SB) mode and interblade (BB) mode due to the coupling between blade and shaft.
The BB mode was of repeated frequencies of (Nb-2) multiplicity for number blades, and the SB mode was of repeated frequencies of (2) multiplicity for number blades.
What is more, with the increase of the number of blades, natural frequency of rotor was decreasing linearly, that of BB mode was constant, and that of SB mode was increasing linearly.
Natural frequency of BB mode was not affected while that of rotor and SB mode was affected (changed symmetrically with the center of shaft) by the position of disk.
In the end, vibration characteristics of coupling mode shapes were analyzed.
