| 摘 要： | 目的研究某核电厂换料水池底部密封结构中密封元件的性能。方法利用有限元分析软件ANSYS,采用超弹单元建立换料水池底部密封结构密封元件的二维轴对称模型,并运用接触单元模拟密封接触界面进行计算分析。结果经计算得到换料水池底部密封结构密封元件的预紧力-变形量曲线。结论计算结果为分析换料水池底部密封结构密封试验的泄漏原因提供了理论依据,同时也为工程中密封元件预紧力的确定提供了较有价值的参考。

| Abstract: | ObjectiveTo study the sealing performance of the floor sealing structure of the refueling pool in a nuclear power plant.MethodsAn axial-symmetry finite element model of the sealing component using super elastic element was built by ANSYS. Then the contact surface of the sealing structure was simulated by the contact element.ResultsA curve between preloaded force and deformation was calculated.ConclusionThe results can be used to solve the test leakage problem of the floor sealing structure of refueling pool and could also be used as a reference in getting preloaded force of sealing components. |
