Performance for rotor system of hybrid electromagnetic bearing and elastic foil gas bearing with dynamic characteristics analysis under deep learning.

The change of the system dynamic stiffness indicates that as the ambient pressure increases from 0.1 MPa to 0.5 MPa, the main dynamic stiffness S xx and S yy of the gas bearing show increasing trends, while the cross dynamic stiffness S xy and S yx show gradually decreasing trends; as the rotating speed of bearing continues to increase, the main dynamic stiffness of the gas bearing increases, while the cross dynamic stiffness shows a decreasing trend.
