    摘要:

    采用SolidWorks软件建立螺旋槽干气密封的动环和气膜的三维模型,用ANSYS Workbench对模型进行单向流固耦合分析,得到动环密封端面的应力和应变分布情况,并研究动环转速和介质气体压力对动环密封端面应力和应变的影响。结果表明,动环密封端面应力和应变主要集中在螺旋槽区域,在螺旋槽根部出现应力和应变的最大值,体现出螺旋槽干气密封很好的动压效应;动环转速和介质气体压力对动环密封端面应力和应变均有较大影响,并且动环密封端面最大应力、最小应力及最大应变和最小应变均随着动环转速和介质气体压力的增大而增加。

    Abstract:

    The threedimensional model of the rotating ring and gas film of spiral groove dry gas seals was established by using the SolidWorks software.The oneway fluid structure interaction analysis was carried out by using ANSYS Workbench software to get the stress and strain distribution of the rotating seal face,and the effect of rotating speed and pressure on the stress and strain at the end surface of the rotating ring was studied.The results show that the stress and strain of the end face of the rotating ring seal are mainly concentrated in the spiral groove area,and the maximum stress and strain appear in the root of the spiral groove,which shows the good dynamic pressure effect of the spiral groove dry gas seal.The speed and the pressure have great influence on the stress and strain of the end surface of the rotating ring,and the maximum stress and strain,the minimum stress and strain of the end face of the rotating ring are increased with the increasing of the rotating speed and pressure.
