Abstract

Dynamic characteristics of a 600MW steam turbine rotor model supported by cylindrical bearings and elliptical bearings were investigated respectively. Differences between the linear and nonlinear characteristics of rotor-bearing systems were studied by numerical simulations, and the performances of rotor systems using different bearings were also presented. Dynamic tests were performed on the 600MW turbine generator group model test rig, while sustained by different types of bearings, to study the oil whirl and whip phenomenon. Comparisons of the numerical results with experimental data show that the nonlinear model is more accurate than the linear model, and the elliptical bearing has the advantage of better dynamic stability over cylindrical bearings.
