Methods of authentication of dynamic models of the rotor systems are developed, in particular, evaluation of coefficients of inflexibility and resistance of the segment bearing of turbocompressor. With the use of the developed methods dynamic coefficients as function from frequency of rotation for all type of bearing which are used in centrifugal compressors presently are collected. Classification of flexible rotors of turbocompressor depending on the choice of optimum planes of correction and frequencies of rotation is resulted, DKV for which needed for a calculation. Job performances are used for the dynamic calculations of turbocompressor on the stage of planning. Product Description popup.authors popup.nrat_date 2020-04-02 Close
