摘要

摘要: 利用Mesh软件建立动环、静环周期模型，基于Workbench对动环、静环进行了三维力耦合和力热耦合计算.探究了力耦合和力热耦合对端面变形的影响，探讨了影响端面变形的操作参数(转速、压差)，并分析了力热耦合产生的应力.得出：力耦合引起周向波度变形和收敛型径向锥度变形，有利于间隙流体的稳定；力热耦合变形中热载荷引起的变形占主导地位；转速对力热耦合变形影响较明显.

Abstract: 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.
