| 文章利用ANSYS有限元软件对压力容器开孔接管区进行应力分析，获得了开孔接管区的应力强度分布图，得到最大应力发生在筒体最高位置与接管的连接处，[HTK]最大应力强度值为247.478 MPa。然后利用ANSYS进行疲劳寿命分析，将有限元方法与疲劳寿命分析理论相结合，得到累积使用系数均小于1，即开孔接管部位满足疲劳强度的要求，因此该容器是安全的。通过此次分析再次证明了ANSYS软件为压力容器实际工程应用中提供了可靠的、高效的理论依据。 |

| In this paper, the application of ANSYS finite element software to analysis the stress of nozzle opening pressure vessel to obtain the nozzle opening stress intensity distribution, the greatest stress is at the highest position in the cylinder connected with the opening tubing and the maximum stress intensity is 247.478 MPa，then using the ANSYS finite element software to analysis the fatigue life of the nozzle opening pressure vessel, which combined the finite element method with the fatigue life theory. At last obtained the cumulative coefficients were less than 1, that is to say that the nozzle opening pressure vessel parts meet the requirements of fatigue strength, result in the container is safe. Through theoretic analysis and the result of finite-element analysis is proved that ANSYS software is acceptable and efficient. At the same time it provides the theoretic support to present pressure vessel engineering. |
