ABSTRACT: In this study, the influence of geometrical
parameters on the curve veering phenomenon in a tor-sional system with stepped
shaft is investigated. Three approximate solutions including finite el-ement,
Rayleigh-Ritz and discretization methods, along with an exact solution are
employed to obtain the natural frequencies of the structure. The study reveals
that, under specific circumstances, the results obtained by approximate methods
are very close to the exact solution. The curve veering behavior is manifested
irrespective of the method employed. It is concluded that for the structure
studied the curve veering behavior is not because of the approximate techniques
used to compute the natural frequencies, and is an inherent behavior of the
structure.
