Dynamics of Gas Bearings of Turbomachines

One way of increasing the frequency of rotation of rotor machines, including, in particular, include turbo-machine, is to install them on gas-static bearings. Turbo-machine with gas bearings have found wide application in the Metalworking, gyroscopes, precision instrumentation, gas compressor stations, etc., what attracts researchers to study the characteristics of their work. The aim of this work is to study the influence of operational and design parameters of gas-static bearings on its dynamic characteristics. The research on contactless bearings, are connected mainly with the study of statistical properties. Therefore, research aimed at improving the stability of the bearings of high-speed machines are, indeed, relevant. The paper presents comparison of results of theoretical and experimental studies of dynamic characteristics of gas-static bearings. The presented method of calculation of the characteristics and experimental studies, as well as ways to reduce vibration and enhance stable operation of turbo machines for gas-static bearings.
