  • A periodical model for rotor-stator rings was constructed with the meshing software, and the 3D force coupling and force-heat coupling behaviors of the rotor-stator system were computed by means of ANSYS Workbench 15.0. The influences of the force coupling and force-heat coupling on the ring end face deformation were investigated. The operation parameters (speed, pressure difference) affecting the end face deformation were discussed and the stresses caused by the force-heat coupling were analyzed. It is concluded that the circumferential wavy deformation and radial tapering deformation generated by the force coupling are beneficial to stability of the interstitial fluid, the deformation generated by the thermal load plays a major role in the total deformation by the force-heat coupling, and the rotation rate has noticeable influence on the deformation by the force-heat coupling.
