| 摘 要： | 在考虑垫片力学性能的非线性和非保守的基础上,提出了承受附加载荷高温螺栓法兰连接结构的有限元分析方法。运用APDL和UIDL,开发了基于ANSYS环境的法兰连接结构强度和紧密性分析模块,实现了连接系统的参数化建模及程序化计算。提出了基于紧密性的承受附加载荷螺栓法兰连接的安全评价方法,并以某铂重整装置接管法兰连接为对象,验证了有限元分析和安全评价方法的可行性,确定了该连接的安全操作条件。

| Abstract: | By considering the nonlinear and nonconservative mechanical performance of gaskets,the finite element method is estabished for analyzing the integrity of bolted flanged connections at an evaluated temperature subject to supplementary loads.A module for analyzing structural strength and tightness of joints has been developed by APDL and UIDL based on ANSYS environment,and then the parametrical modeling and programmed calculation are realized.The safety assessment method for bolted flanged connections subject... |
