摘要：

Recently, Crandall and Yeh (1989) reported an interesting phenomenon in the Campbell diagram of a single spool machine. In their words, "It is interesting that ... the two modes form a coupled system and the curves repel each other avoiding an intersection" in the Campbell diagram, which is the so-called curve veering in the eigenvalue problem. In this paper, the existence of the curve veering in the eigenvalue problem of general rotor-bearing systems are verified and the criteria of the curve veering is evaluated. The abrupt but continuous changes of mode shapes during veering are also illustrated.
