Wang L.
Abstract
For 200MW turbine set, considering higher¡¡order and higher dimension of nonlinear differential equations governing the motion of its rotor-bearing system, the Mechanized Mathematics can be used as modeling and analyzing means of rotor-bearing system after reducing order of differential equations by Component Mode Method, in order to obtain the analyzed solutions of the 200MW turbine set. Lower dimension algebraic equations included nonlinear oil force expressions are obtained, because of the nonlinear parts of oil force expressions can be remained after eliminating the linear coupling variable of node displacements of rotor-bearing system of 200MW turbine set. Differential Control Algorithm (DCA) that is different to both analyzed method and typical numerical method is presented. According to proposed method the model of 200MW turbine set is described and node displacement response of set is analyzed and predicted.
