高低压转换装置的应力与疲劳分析研究

Stress and fatigue analysis of pressure exchange device

鉴于深部矿井热害问题的日益严重,以高低压转换装置为核心的地面集中矿井降温系统得到越来越多的应用;由于高低压转换装置承受的压力处于周期性变化状态,因此,会导致装置的疲劳破坏;为了确定该装置设计参数是否满足疲劳寿命的要求,采用ANSYS软件对其应力分布及疲劳性能进行分析,确定装置的安全性和可靠性。

In view of gradually severe thermal disaster in deep mines, the ground centralized mine cooling system whose core is the pressure exchange device gets more and more application. Since the pressure of the device varies periodically, fatigue damage occurs. In order to determine the design parameters of the device whether met the requirements of the fatigue lifespan, ANSYS was applied to analyze the stress distribution and the fatigue performance, so as to guarantee the safety and reliability of the device.
