Abstract

Numerical and experimental investigation of dynamics for simulator of compact gas turbine rotor in foil gasdynamic bearings is carried out. For definition of influence on rotor-simulator—gas bearings—casing system dynamics from main parameters such as rotor imbalance and structural damping, the series of rotor, casing, foil bearings and gas lubrication finite-element models are developed. Influence of gas foil bearing design and temperature state is considered. In experimental part of work the rotor floating up in bearings conditions are determined for operation in normal conditions and at 420 °C heat. Estimation of coatings in support durability was carried out at cyclic start-stops. For calculated and experimentally obtained rotor orbits the system main frequency characteristics were determined using spectrum analysis. Rotor system sensitivity for changing main parameters is shown. Numerical simulation and experimental results provided additional tools for analysis of effects observed in experiment and for numerical model verification.
