Ying Cui, Auteur ; Zhansheng Liu, Auteur ; Daren Yu, Auteur |A nonlinear dynamic model is developed for a rotor-bearing system with radial steam force due to partial admission, taking into account the prediction of subsynchronous instability of a steam turbine. The optimum schemes are obtained by comparin[...]
