摘要
简要介绍了球阀疲劳磨损产生的原因和机理,以ANSYS Workbench有限元分析软件为基础建立了球阀密封模型,分析了球阀压力载荷的变化对阀体疲劳寿命所产生的影响,并提出了相应的改进措施和延长球阀使用寿命的方法。
: The causes and the mechanism to the ball valve of fatigue wearing are introduced. Using the finite element ANSYS Workbench analysis the ball valve fatigue life and descript the impact of changes in pressures load. And make some measures to improvement the ball valve fatigue wear and to extend the fatigue life.
