Prediction of the vibration state of the GTE turbine rotor taking into account the influence of the geometric accuracy of parts

[摘要] The article deals with the problems of ensuring the vibration of gas turbine engines. A technique has been developed for assessing the level of vibration state depending on the geometrical errors of parts and assembly units. The studies of the level of vibration state are presented depending on the following geometrical parameters: eccentricity of the inner hole of the shaft and eccentricity of the supports. A regression dependence of the level of vibration velocity on the considered geometrical errors is formed.
