| 摘 要： | 运用CATIA软件建立了与真实辅助泵完全一样的三维模型,使用四面体单元对建立的模型划分有限元网格,克服了采用壳体单元的近似,使模型的计算结果更加可靠。计算了反应堆用辅助泵的抗震性能,在地震载荷、温度场的作用下,最大Mises等效应力为15.8MPa,小于应力极限值132.825MPa,辅助泵完全满足相关规范抗震强度的要求。

| Abstract: | A 3-dimension pump model which has the same size as the real pump is built in CATIA software.Tetrahedron element is uscd for the finite element method. The method overcomes the approximation of using shell element and thus makes the result more reliable. The strength of auxiliary reactor pump is calculated under seismic load and temperature field. The maxim Von Mises stress is 15.8 MPa, which is smaller than strength 132.825 MPa. The auxiliary pump is safe and fulfills the requirement of standard document. |
