摘要:
为了研究剖分环式快开门压力容器的应力分布规律，识别其应力集中区域，找到此类压力容器的易破坏区,利用有限元分析软件ANSYS，整体分析计算了内径为560 mm的三瓣式剖分环快开门压力容器.为减小计算量，根据该结构轴对称性，建立了三分之一的三维实体模型.根据实际情况限定边界条件为：在容器内施加45 MPa内压，对称面上施加对称约束，容器底部施加固定约束.经过非线性分析计算，求出该结构的整体应力分布云图，得到整体结构和剖分环、平盖、筒体的应力集中区域及其应力分布规律.然后，采用分析设计标准JB4732-95对该压力容器各个组件的危险截面分别沿轴向和径向进行了路径评定，评定结果显示所选的结构设计合理，强度符合设计要求,对同类结构的设计制造具有一定的参考价值.
Abstract:
To study the stress distribution and identify the stress concentration area of the split quick closure pressure vessel, which is easy to find the damage area of this kind of pressure vessel, finite element analysis software ANSYS was used to analyze and calculate the 3 valve type of the split quick closure pressure vessel whose inner diameter is 560 mm. To reduce the amount of computation, a third of 3D entity model was established according to the symmetry of the structure. According to the actual situation, boundary conditions were limited as follows: 45 MPa pressure was applied in the container; symmetry constraints were imposed on the symmetry planes; fixed constraints were imposed at the bottom of the container. Through nonlinear analysis and calculation, the integral stress distribution nephogram of the whole structure is obtained, and the stress distribution rules and stress concentration area of the overall structure, split ring, flat cover and cylinder of the device were discovered. Though path assessment on the dangerous section of the pressure vessel components along the axial and radial path respectively based on the analysis design standard JB4732\|95, results show that the design of the selected structural is reasonable and the strength complies with the design requirements, which provides a certain reference value to the design and manufacture of similar structure.
